This application is a copending US patent application filed on November 17, 2004, which is a continuation of US Patent Application No. 10 / 714,814, filed November 17, 2003. No. 10 / 991,135, the contents of both patent applications are hereby incorporated by reference in their entirety. This application claims priority to US Provisional Patent Application No. 60 / 672,502 filed on April 19, 2005, under section 119 (e) of the US Patent Act. The entire contents of this application are also incorporated herein by reference.

  In Fiber-To-The-Premises (FTTP) broadband network applications, an optical splitter is used to split the optical signal at various points in the network. Recent network specifications require the incorporation of an optical splitter in a fiber distribution hub (FDH), which is a re-entry outdoor enclosure. These enclosures allow easy re-entry to access the optical splitter, so that more splitter ports can be added incrementally while efficiently using the splitter ports.

  In conventional conventional applications, the optical splitter is provided prepackaged within the optical splitter module housing, and the splitter output is provided as a pigtail extending from the module. These splitter output pigtails are typically provided with a high performance, low loss, simple connector (SC) and / or LC connector. This optical splitter module (or cassette) provides protective packaging for the optical splitter component in the housing and thus provides easy handling of the otherwise fragile splitter component. According to this method, for example, an optical splitter module can be incrementally added to the FDH as needed.

  Problems arise due to the lack of protection and organization of the connector end of the splitter output pigtail. For example, these pigtails are often left hanging in cable troughs or raceways in the enclosure. If optical components such as high performance connectors are left exposed, they are likely to be damaged. Damage to these high performance connectors can cause service connection delays while the connectors are repaired. Further, if the splitter output pigtail with the connector is left hanging in the cable trough, it is exposed to dust and dirt in the cable trough. In the current network deployment situation, it will be important to keep the optical connectors clean to maximize network performance.

  Furthermore, fiber pigtails in current technology are organized in a manner that is not useful for rapid service delivery. In many cases, the splitter can have 16 or 32 output pigtails tied together, making it difficult to find a specific pigtail. Also, loose and sagging pigtail bundles can easily droop and / or be damaged, resulting in further delays in service delivery. These drools cause congestion and, in some cases, cause bend-induced losses to the pigtail, resulting in reduced system performance.

  In order to overcome some of these problems, conventionally, separate storage trays or enclosures have been utilized to remove slack and / or to store and protect the connector end of the splitter output pigtail. However, these auxiliary devices occupy more space and often obscure the pigtails in the enclosure, tending to make it difficult for track engineers to find specific pigtails and / or connectors. Have. This results in a delay in the deployment of new subscriber connections depending on the amount of time required to access the fiber pigtails in the enclosure. Accordingly, there is a need for a solution that provides convenient storage of fiber pigtails and / or connectors and does not occupy additional space within the enclosure. This solution needs to provide direct access to the fiber pigtails and / or connectors and their identification.

  Finally, current methods tend to result in the loss of the association between the end of the splitter output pigtail and the splitter module. Pigtails usually produce this result because once deployed, they are misplaced in the fiber jumper trough among other pigtails. When a subscriber is taken out of service, it is desirable to disconnect the splitter output and redeploy it or save it for easy redeployment. It is further desirable for management to maintain an association between the splitter module and the splitter output pigtail so that resources are effectively used over time.

  FDH can benefit from apparatus and techniques that can be adapted to smoothly perform the organization of fiber pigtails and fiber pigtail terminations and protection of sensitive optical components when not in use. These devices and techniques also need to smoothly provide easy access to pigtails and connectors so that subscribers can be efficiently connected and disconnected from the network. These devices and techniques also need to group pigtails and connectors in a manner that can be associated with a particular splitter module.

  According to one implementation, a parking adapter is provided. The storage adapter can include a plurality of containers configured to accommodate a plurality of similar connectors, where each connector is associated with an optical fiber. The storage adapter can include a dust cap post configured to receive a connector dust cap associated with at least one of the plurality of connectors. The storage adapter can include an attachment device configured to removably couple the storage adapter to the panel.

  According to another implementation, an enclosure is provided that is adapted for use in an optical communication network. The enclosure can be pivotally supported within the enclosure and can include a first access door adapted to smoothly provide access to the interior of the enclosure when the first access door is in the open position. The enclosure can include a hinged panel adapted to be present inside the enclosure when the first access door is in the closed position. The hinged panel is also adaptable to support a storage adapter configured to accommodate a connector associated with the optical fiber routed within the enclosure, in which case the optical fiber is connected to the destination device. If it is not associated with the transmission of the optical signal to, it will be accommodated. The storage adapter can also be configured to accommodate a connector dust cap associated with the connector or an adapter dust cap associated with the adapter. The enclosure can include a subscriber termination area adapted to provide an optical signal to a destination device.

  According to yet another implementation, a method for configuring an enclosure in an optical communication network is provided. The method can include removing the connector from the storage container associated with the storage adapter, wherein the storage adapter is associated with the hinged panel. The method can include supporting a connector dust cap on a dust cap post associated with a storage adapter, wherein the connector dust cap is associated with the removed connector.

  As outlined, an optical splitter module with an adapter for preserving the end of an optical splitter pigtail with a connector is disclosed. The adapter is placed on the optical splitter module bulkhead in an octal count configuration that is ideally adapted to identify, for example, a splitter port with 16 or 32 output ports (provided that But not limited to this). The adapter according to the preferred embodiment is used to store or stage the connectorized end of the optical splitter to quickly find, identify, easily access and remove the pigtail output end.

  The network 10 uses an OLT 12 that receives an input data stream from a service network. As an example, the OLT 12 can receive an audio input 14, a data input 16, and a video input 18. The OLT 12 can then output the multiplexed data stream on one or more optical fibers 20. In one embodiment, the OLT 12 can output audio at a wavelength of 1490 nm, data at a wavelength of 1310 nm, and video at a wavelength of 1550 nm. The optical fiber 20 can transmit data to a passive optical splitter (POS) 22 using, for example, wavelength division multiplexing (WDM). The POS 22 receives data through a single fiber (input fiber), and can divide this data across a plurality of output fibers. For example, the POS 22 can divide incoming data across 8, 16, 32, or more output fibers. In the preferred embodiment, each output fiber is associated with a respective end user, such as a residential end user 27 or a commercial end user in an office building 28. At the end user's location, optical network terminal (ONT) 24, 26 is available which receives the multiplexed data and provides it to the end user. For example, the ONT 24 receives a multiplexed data stream containing voice, video, and data and acts as a demultiplexer by demultiplexing the data stream to provide separate voice channels to the user's telephone. Video channels can be provided to a television set and separate data channels to a computer.

  The architecture described in connection with FIG. 1 may be, for example, a point-to-multipoint PON structure utilizing a 1:32 splitter in a fiber hub enclosure in the wiring area. This architecture may be 1: 1 wiring occupying the fiber between the fiber hub and the customer premises, or the architecture may be sparse 1: X, where X is An integer greater than 1). Broadband service capabilities of the network 10 that distributes source information include, for example, data signals (622 Mbps x 155 Mbps (shared)) and video signals (860 MHz, ~ 600 analog and digital channels, HDTV (High Definition Television), and VOD ( Video On Demand)). The source information can be composed of data such as voice or video derived from a source such as a communication service provider (hereinafter referred to as a service provider). Signaling can be implemented using Wavelength Division Multiplexing (WDM) and fiber sharing. The network 10 is scalable and can include an ONT 26 that provides high-bandwidth multi-service applications that serve residential and small and medium sized businesses. The network 10 includes passive components that are located outside the plant (ie, outside the service provider building) and require minimal maintenance because no active components such as amplifiers are required. Yes.

  Broadband access network 10 includes a digital subscriber having a wideband termination adapter configured to receive a digitally multiplexed wideband data stream and to output a plurality of demultiplexed wideband data streams to individual subscriber loops. Includes plug inline card.

  FIG. 2 shows an alternative implementation 50 of an optical broadband access network. The network 50 can include circuit switching / OLT 52, SAI, splitter hub 54, residential ONT 56, small business ONT 58, office park ONT 60, splitter 64, and FTTP (Fiber-To-The-Premises) 62. In an HTTP broadband network application, an optical splitter 64 is used to split the optical signal at various points in the network. Within the FTTP network 50, optical splitters are typically located in both indoor and outdoor environments including central office / headends, environmentally protected cabinets, enclosures, or fiber drop termination devices. In some outdoor applications, the light splitter is deployed in a tightly sealed environmental enclosure that is not easily reentrant. The preferred embodiment includes an optical splitter built into a fiber distribution hub 54, which is a reentrant outdoor enclosure. These enclosures allow track technicians or other service personnel to easily re-enter to access the optical splitter 64, thereby effectively utilizing the splitter port and incrementally adding additional splitter ports. Can be added.

  The preferred embodiment of the present invention is prepackaged in an optical splitter module housing mounted in a fiber patch panel to facilitate routing of jumpers interconnected from the fiber in the adjacent subscriber port to the splitter output. The data can be received from the optical splitter provided in the prepared state. This optical splitter module (or cassette) provides protective packaging and thus easy handling of otherwise fragile splitter components. These optical splitter modules can be added incrementally to the patch panel.

  The FTTP broadband network is designed to achieve low optical insertion loss in order to achieve maximum network reach from an electronic circuit with a fixed power output. Each optical component and subsystem utilized in the network is optimized to provide minimal insertion loss. The expected value of light loss in the preferred embodiment is about 23-25 dB for a 1:32 passive split. Factors and factors contributing to optical loss are splitter (1:32, single or cascade), WDM, connector (OLT (Optical Line Terminal), FDF, splitter, drop, ONT), fiber attenuation (at least 1310 nm, 1490 nm). And at three wavelengths of 1550 nm) and junctions.

  Splitter hub 54 is serviceable at a 128 splitter port / premises level. This includes a plurality of distribution cables with connectors or melt bonded between the splitter and the distribution hub 54. The splitter hub used in connection with the preferred embodiment can be mounted on a utility pole or on the ground. The drop termination device may or may not include a splitter and can include a variable number of drops (both airborne and embedded).

  The splitter 64 can be deployed via the splitter hub 54, or it can be deployed in a small enclosure. The fiber drop termination device 65 is often used in the context of a utility pole 63 (FIG. 2). The utility pole 63 can be used to support conventional copper strands such as those used in POTS (Plain Old Telephone Service) and those used in CATV (Cable Television). For example, a POTS wire strand can be composed of a plurality of twisted pairs, and a CATV can be composed of a coaxial cable. The utility pole 63 can also support a bundle of optical cables such as those used to provide the HTTP service. The fiber drop termination device 65 can be attached to the utility pole 63 and can be communicably coupled to one or more of the optical fibers contained in the strand. The fiber drop termination device 65 can be bonded to an optical fiber by using techniques known in the art. For example, the fiber drop termination device 65 can be bonded to the optical fiber at a predetermined location of the strand in the manufacturing or assembly plant, or the fiber drop termination device 65 can be installed on site by a track maintenance technician or other technical personnel. Can be bonded to an optical fiber at a predetermined location.

  In a passive optical network (PON) application, a fiber drop terminator is used to interface between a distribution cable and a drop cable. The fiber drop termination device 65 is usually installed by joining multi-fiber cables at the branch point of a distribution cable having a large number of fibers. Fiber drop termination devices can typically be composed of 2, 4, 6, 8, or 12 fibers, and in some instances, a greater number of fibers. A single cable can be used as input to a termination device containing the aforementioned number of fibers. As an example, the feed cable can include a central tube that houses a plurality of individual optical fibers. Inside the fiber drop termination device 65, the multi-fiber feed cable is separated into individual fibers and then terminated by individual rugged outdoor connectors / adapters located on the outer surface of the enclosure. Thus, by using the fiber drop termination device 65, the PON wiring system is staged near a premises location such as a residence or office building, so that when a subscriber requests service, the fiber drop termination device 65 A drop cable with a simple connector can be quickly connected between the device and an optical network terminal device (ONT) at home.

  In some embodiments, optical connectors are used in the network to provide the desired flexibility, but these are limited to points in the network where absolute flexibility is required. . An optical connector is necessary to provide flexible access to the optical splitter output. The preferred embodiment of the present invention minimizes optical loss while providing connector flexibility by using an optical splitter module having a pigtail with a connector. These pigtails can be equipped with standard SC or LC type connectors at the ends.

  FIG. 3A illustrates an optical splitter module 100 in a fiber distribution network with a connectorized pigtail according to an exemplary embodiment. Module 100 can contain essentially any number of output pigtails, but in a typical deployment, it would utilize 16 or 32 outputs per splitter module. The module 100 includes a bulkhead faceplate 102 with a storage container 112. In one embodiment, the optical splitter module 100 provides a high density ribbon wiring harness 106 to protect the splitter output extending from the module 100. The ribbon harness 106 of the optical splitter module is secured to the module 100 by a strain relief mechanism 104 to provide high tensile strength and bend radius control. The compact nature of the ribbon harness 106 achieves a relatively high packing density in the cable trough and a relatively good space utilization. By converting this module harness into individual pigtails with connectors, the splitter outputs can be individually managed and relocated.

  The module 100 can comprise a semi-function adapter or a full-function adapter as a means for preserving the end of the pigtail. In the preferred embodiment, the semi-functional adapter is used in applications that do not require a fiber optic terminator other than the storage function. Full-function adapters are used in applications that require the connection of a fiber optic terminator to the optical splitter output port. Access to the ferrule end of the pigtail will be required to remove unwanted reflections caused by unterminated connectors by installing a fiber optic terminator. This module provides a home position where the optical splitter output pigtail can be deployed from here when starting the service and the splitter output pigtail is returned here when closing the service. Can do. Such administrative use of the adapter provides protection of the pigtail end with the connector, keeps the connector end clean and allows for quick service connection and deployment.

  Embodiments of the present invention are directed to a fiber wiring hub configuration having an optical splitter module with a fixed-length connectorized pigtail. In one aspect, the location of the optical splitter module is determined relative to other fiber terminations that require access to the optical splitter port. These embodiments also provide for pigtail placement in a configuration that allows sufficient or slack to reach all of the fiber terminations that require access to the splitter port while requiring minimal pigtail relocation and loosening. Is also provided. The method of installing the pigtail of the optical splitter module determines how to route the pigtail to provide an optimal routing scheme that is not congested and that can control slack within the set limits of the enclosure. Includes stages. These methods can include making all pigtails the same length to facilitate manufacturing and customer ordering. Splitter modules, all with the same pigtail length, are also flexible and easy to install in any available slot in the patch panel, regardless of their sequential order. Realized. The fixed-length pigtail is preferable for many applications, but the embodiment is not limited thereto. If necessary, variable length pigtails can also be used.

  One embodiment of installing the splitter module pigtail also provides for the management of the fiber within the enclosure so that the rearrangement and heavy movement do not impede the management of the pigtail. In order to achieve this, the possibility of access blocking due to loosening and fiber twisting is minimized. Some embodiments allow intense movement over time, including initial pigtail storage, service connection, service disconnection, and repetitive storage to provide easy access for future use. ing. This method does not result in interruption and congestion of jumpers routed in the cable path and fiber patch panel. The method can be completely encompassed within the boundaries of the enclosure.

  FIG. 3B shows a diagram of optical component modules (OCM) 107A-D within the fiber wiring hub enclosure of module chassis frame 101 according to one embodiment of the present invention. This FDH configuration provides fiber management hardware on one side of the cabinet. Thereby, the fiber jumper can be routed between the terminal shelf and the splitter shelf. By using a slack loop, excessive slack can be managed at the side of the cabinet.

  According to one embodiment, the OCM modules 107A-D can include a pigtail 105 to reduce the number of connections in the network. The modules shown in FIG. 3b can each include a 1 × 32 splitter with pigtails provided at the input and 32 outputs. The connector end of the pigtail is stored on the bulkhead adapter 103 on the front of the module. These storage adapters provide a skilled spare pigtail detection scheme so that the end of the connector can be quickly identified and connected to the wiring fiber. The adapter spacing is the same as in a standard connector panel.

  In some embodiments, the OCM module can also include a standard terminator. A module terminated by the bulkhead adapter 103 can have a terminator on the front of the module. Modules connected via pigtails and equipped with storage adapters have terminators on the back of the panel.

  FIG. 4A schematically illustrates installation of a pigtail 138 of an optical splitter module according to one embodiment of the present invention. Embodiments of the present invention include an FDH 127 wiring installation layout 125 that includes a splitter module 132 that is incrementally installed on a shelf 129 adjacent to the subscriber termination field 128. Pigtails 138 with connectors from splitter modules 132 having the same fixed length are routed in a circumferential path 130 surrounding the subscriber termination field 128. The connectorized end of the pigtail 138 is stored at a position in front of the splitter module 132 by using a storage container 134. The layout according to this preferred embodiment utilizes a fan through arrangement so that the splitter module pigtail can be installed without interfering with the installed pigtail already connected to the subscriber termination field 128. . This installation layout according to the preferred method of the present invention also ensures that the splitter module 132 is pre-configured in the storage position by the pigtail connector 135 and can be left in the storage position throughout the pigtail installation process. .

  FIG. 4B schematically illustrates the service connection configuration 150 of the optical splitter module according to one embodiment of the present invention illustrated in FIG. 4A. Embodiments of the present invention first connect individual subscribers to service by disconnecting individual splitter output pigtails 138 from storage locations in splitter module 132 and then routing the pigtails to the desired subscriber port 152. A service connection method is included. Since the pigtail harness is pre-configured and routed circumferentially around the subscriber end, the pigtail 138 essentially reduces the distance of the circumferential path simply by Reach all of the desired subscriber ports in the target population. By reducing the circumferential path, the pigtail slack will have further slack. This further slack can be handled by using a slack half-loop in the vertical channel (or pigtail channel) 153A, 153B to which the pigtail is routed. Such random characteristics of connecting the splitter output pigtail to the subscriber port 152 result in a group of various sized half loops 154 managed in the vertical channels 153A and 153B within the boundary of the cabinet 149. Will bring.

  5A and 5B schematically illustrate the installation of the pigtail of the optical splitter module 132 and the service connection configuration of the optical splitter module 132, respectively, in a network having adjacent modules according to an embodiment of the present invention. One embodiment of the present invention includes a method for connecting subscriber ports that are present in adjacent fields but are not initially included within the circumference 178 of the splitter pigtail harness. In this case, the splitter output pigtail is routed to an adjacent field 180 with a path at the same distance to the subscriber port in the circumference by the parallel position. Also, the subscriber ports 192 (FIG. 5B) in these adjacent fields are randomly assigned, so the resulting slack is to use groups of various sized half loops in the vertical channel 176. Is managed by.

  5C and 5D schematically illustrate termination and splitter field service connection configurations 194, 206 in adjacent fiber wiring hubs in accordance with a preferred embodiment of the present invention. In the preferred embodiment, the pigtails 198, 208 of the left modules 196, 214 are routed circumferentially in the clockwise direction, and the pigtails 204, 210 of the right modules 202, 216 are circled counterclockwise. It is routed around. The fiber wiring hubs in this embodiment are arranged adjacent to each other, each comprising a splitter shelf with a splitter module and a termination shelf. The counter-rotating feed scheme provides routing of the circumferential splitter module output pigtail around the subscriber termination field. Pigtail slack is stored in the vertical channels 200, 212.

  One embodiment includes a method of removing a splitter pigtail from a subscriber port 192 and redeploying its output pigtail to a new subscriber port, or storing the pigtail back to the original storage location of the splitter module 132. It is out. This method is due to planned slack management and is not accompanied by blockage or congestion.

  Most embodiments of the optical splitter module 132 used in the FDH 127 have 16 output ports or 32 depending on the particular network configuration, including considerations regarding optical expectations associated with the optical splitter and associated network reach. Number of output ports can be provided.

  FIG. 6A shows a double width module 224 with a width (W2) 232 that is twice the level of W1, along with a single width module 222 with width (W1) 230. FIG. The optical splitter modules 222, 224 may be terminated at the output ports on the bulkhead faceplates 227, 229 by using connectors and / or containers 228, 238, 240, or alternatively, for example, As shown in FIG. 4A, an output port in the form of a pigtail 138 extends from the bulkhead faceplate and is staged back to storage ports 226, 234, 236 located on the faceplate. A typical configuration can be provided. In at least one design implementation, the 16-port module 222 can be deployed as a single-wide module W1 (230) with output or storage ports arranged in a single column on the faceplate 227. And according to the same design implementation, the 32-port module 224 is a double-width W2 (232) module with output ports 234 or storage ports arranged in 16 two columns on the faceplate 229, respectively. It is.

  When used with pigtails and storage ports, a multi-fiber pigtail harness and its associated individual pigtail breakout to store a protective splitting device that converts multi-fiber cables to individual fiber pigtails Space in the enclosure is consumed. The space for storing the splitting device (or transition unit) 131 (FIG. 4A) is designed so that splitting from two 16 output port modules 222 or one 32 output port module 224 can be used. Furthermore, the space for storing the transition portion 131 can be arranged at a fixed distance along the circumferentially routed splitter output harness. Therefore, the space in the chassis that is allocated to install the splitter module corresponding to the fixed storage space of the transition part 131 needs to allow the installation of two 16-output port splitter modules 222 or one 32-output port splitter module 224. .

  In certain situations, it may be desirable to employ a configuration that utilizes an installation sequence that installs the 16-port module 222 in the gap between the two 32-port modules 224 without any space between adjacent modules. Let's go. Such a configuration can pose a problem if only insufficient space is provided to accommodate the transition portion 131. Examples of problems that may occur can include blockage and congestion. By utilizing pair-wise installation of single-width modules 222 (eg, 16 output port modules) in a double-width slot, it is stored and fixed at a location away from the splitter module within the designated storage area 133 of the enclosure 127 Correspondence of the length wiring harness transition part 131 can be maintained.

  Embodiments of the present invention are directly adjacent to the 16-port single-width module 222 in situations where single-width 16-port modules are not installed in pairs (ie, two 16-port modules are not installed directly in parallel). Thus, a structure and method is utilized that allows the user to abandon installing the 32-port double-width module 224, alone or in combination. The technique utilized in the preferred embodiment includes an automatically indexed latch that substantially maintains pair-wise installation of a single-width 16-port module in the same location as a dual-width 32-port module. We are using.

  FIG. 6B is associated with a splitter module to ensure that two single-width 16-port splitter modules are installed in a pair-by-pair arrangement in the same space that would otherwise accept a single-width 32-port splitter module 254. FIG. 9 illustrates an embodiment utilizing a unique chassis bulkhead mounting configuration of the splitter module in combination with a unique latch configuration. FIG. 6B includes a bulkhead 250 with an upper mounting rail 251A and a lower rail 251B defining an opening 257 that accommodates a double width splitter module 254 and a single width splitter module 260. The double width module 254 includes an upper mounting hole pair 256A and a lower mounting hole pair 256B on the faceplate, together with a first bank 255A and a second bank 255B of containers. Single width module 260 includes an upper mounting hole 261A and a lower mounting hole 261B, and a single bank 263 of containers. Further, the single width module 260 and / or the double width attachment module 254 can include attachment latches.

  The FDH chassis is supplied with a bulkhead 250 that provides an opening 257 for receiving the splitter modules 254, 260 in combination with mounting holes that receive the splitter module latches directly above and below the opening in the bulkhead. ing. The pattern of module mounting holes on the bulkhead of the FDH chassis consists of four holes per double-width module 254, which are two holes 256A at the top of the opening and two holes 256B at the bottom. It is divided into This arrangement is such that each set of holes is offset toward the center so that they are evenly spaced in the center normally expected when single-width 16-port modules 260 are installed in the same space. Has a unique configuration. This unique bulkhead mounting configuration ensures that the double width module 254 cannot be installed directly adjacent to the single width module 260 unless the two single width modules 260 are installed in a pair-by-pair arrangement. As a result, the storage area of the splitter output pigtail splitting device on the FDH chassis located away from the splitter module located at a fixed distance from the splitter module along the circumferential length by guaranteeing pairwise installation Proper use of is enforced.

  To ensure correct installation, the 16-port single width module 260 allows the single width module 260 to be placed in the bulkhead opening while allowing a slight offset to the left or right of the latch. It has an indexing latch function having a unique shape. This unique latch function is the bipolar holes 261A, 261B having a physical shape that shifts the latch of the single-width module to the left or right during installation to achieve alignment with the holes off-center.

  In addition, the slotted holes of the single-width module 260 have a unique shape that allows the standard fasteners commonly used in this type of module to be fixed in place on the left or right. This slot-shaped hole is attached so that when the single-width module is installed in the left position (or center left), the fastener grommet is in the center right, and the single-width module is in the right position. In order to latch to the left of the center, it has a unique heart or bilobal shape. The heart-shaped slot basically latches with sufficient force to seat the grommet and firmly place and secure the module in place without a subsequent shift in the bulkhead opening. Is indexed left or right.

  6C-6H illustrate aspects of the keying mechanism used to align the 16 and 32 output splitter modules in the desired pattern.

  7A-7E show views of a fiber distribution hub according to one embodiment of the present invention. The FDH according to one embodiment manages a connection between a fiber optic cable and a passive optical splitter in an OSP (Outside Plant) environment. These enclosures are used to connect the feeders and / or wiring cables via optical splitters to provide distributed services in an HTTP network application. The preferred embodiment FDH provides a cross-connect / interconnect interface for optical transmission signals in locations within the network where fiber hubbing, operable access, and reconfiguration are critical requirements. ing. In addition, this FDH is designed to support factory installations of pigtails, fanouts, and splitters while accommodating sizes and fiber counts within a given range.

  According to a preferred embodiment, the FDH is provided in a pole mounting or pedestal mounting configuration. The same cabinet and work space are available for both pole mounting (FIGS. 7A and 7B) and pedestal mounting units (FIGS. 7C, 7D, and 7E). Typically, for example, three sizes of FDH can be used to accommodate three different feeder numbers (eg, 144, 216, and / or 432, etc.), but without limitation. It is also possible to use an FDH of a certain size.

  The FDH embodiments of reference numbers 280, 290, 300, 310, 320 provide termination, bonding, interconnection, and partitioning within a single compartment. These enclosures contain metallic or dielectric OSP cables through sealed grommet outlets. The cable is secured by a standard gripping clamp or other means known in the art. FDH can also provide grounding for metallic members and cabinets.

  Enclosures 280, 290, 300, 310, 320 provide environmental and mechanical protection for cables, joints, connectors, and passive optical splitters. These enclosures are typically manufactured from heavy gauge aluminum and are NEMA-3R compatible and are required for rain, wind, dust, rodents, and other environmental pollutants. Provide protection. At the same time, these enclosures are lightweight for easy installation and are breathable to prevent moisture accumulation in the unit. The aluminum structure with a heavy powder coat finish also provides corrosion resistance. These enclosures are accessible through secure doors that are locked by standard tools or padlocks.

  FIG. 8 shows a diagram of the internal components of a fiber wiring hub enclosure 350 according to one embodiment of the present invention. The FDH enclosure 350 can be configured in several different ways to support fiber cable termination and interconnection to a passive optical splitter. The configuration shown in FIG. 8 provides a termination shelf 352, a splitter shelf and optical component module 354, a splice shelf 356, and a fiber management channel 358.

  Termination shelf 352 may be based on a standard (Main Distribution Center: MDC) enclosure line that provides complete management of fiber terminations according to one embodiment of the present invention. Termination shelves can be pre-terminated at the factory, for example, with stub cables containing 72, 144, 216, 288, or 432 fibers. By using this stub cable, the service is connected to the distribution cable routed to the house. The wiring fiber is terminated with a certified connector. These termination shelves can use, for example, standard 12-pack or 18-pack adapter panels that are ergonomically designed to provide easy access to fiber terminations in the field. These panels can be mounted on a hinged bulkhead to allow easy access to the back for maintenance. The fiber jumper is organized and protected with the transition to the fiber management section 358 of the enclosure.

  The splitter shelf 354 may be based on a standard fiber patch panel that houses a standard optical component module (OCM) that holds an optical splitter according to a preferred embodiment of the present invention. In the preferred embodiment, the splitter module (or cassette) is designed to simply snap into the shelf and thus can be added incrementally as needed. Splitter shelf 354 functions to protect and organize the input and output fibers connected to the cassette. Various sizes of splitter shelves 354 can be used, and the size of the shelves can be optimized for various OCM module configurations.

  FIG. 9 shows a schematic diagram of a fiber distribution hub enclosure 380 having a parallel device configuration according to one embodiment of the present invention. There are two adjacent termination shelves 388, 390 and two adjacent splitter shelves 384, 386 separated by a central fiber management channel 382 in accordance with one embodiment of the present invention.

  The FDH can be installed in a utility pole or pedestal configuration that requires the back of the enclosure to be held fixed. In these situations, the end of the cable or fiber cannot be accessed through the back of the cabinet. In normal management of FDH, track engineers will need to access the back of the terminating bulkhead and perform maintenance work on the connectors on the back. One such operation is to clean the connector and remove dust and / or contamination that can reduce the performance of the components within it. In addition, the back of the FDH enclosure would have to be accessed for troubleshooting the fiber, such as what happens with fiber breakage or fiber breakage. In addition, it is necessary to access the back of the enclosure when adding cables for maintenance upgrades, performing branch junctions using FDH as the origin, and routing specified fibers to alternative locations, etc. Let ’s go. In such situations, access to the back of the enclosure may be difficult unless a back door or access panel is provided. Access to the back of such an enclosure would require disassembly of the equipment chassis and / or wiring equipment to provide access to fiber connectors or cables.

  The configuration to provide access at the rear of the chassis must be carefully planned to minimize fiber movement during operation. For example, a configuration can be devised to move the end, not the splitter pigtail. Such a configuration can impose excessive stress on the terminations and / or pigtails as one section of the device moves while another remains stationary. A device that includes partial movement to access the connector would not be suitable for adding additional capacity to the wiring system and maintaining it. If the equipment tray is slid or the bulkhead panel equipment is tilted for maintenance access, stress points are created in the fiber cable and certain other areas of the chassis tend to be blocked. Would therefore not be a desirable alternative to an enclosure with a removable back panel.

  FIG. 10 shows access to all optical components for cleaning and testing and access to cables for maintenance or addition by swinging the entire chassis including optical connectors, splitters, and joints open 90 degrees or more. 1 illustrates a preferred embodiment of an FDH enclosure 301 designed to have a unique swing frame chassis 322 that permits This swing frame design provides the equipment necessary to add additional cables into the unit for future use that will require full access to the back of the cabinet. For example, access to the back penetrator punchout 320 is possible by opening the swing chassis to the open position. Once the punch-out has been removed, weatherproof feedthroughs can be installed and then multi-fiber cables can be passed through the enclosure through these feedthroughs.

  One embodiment of the FDH cabinet 301 can include a single point swing frame release latch 326 that provides easy access to the back surface and firmly locks the chassis in place when closed. Release latch 326 can be positioned as shown in FIG. 10 and / or release latch 326 can be positioned at the bottom of the enclosure. In addition, providing a lock to keep the chassis open at various angular increments can reduce the chances of track technicians being injured when working on components located behind the bulkhead 335. is there. If it has a lock to hold it open, the chassis 322 is called a self-locking chassis. In the embodiment of FIG. 10, the entire chassis is hinged, providing a single bend in the fiber cable routed to the chassis. This hinge point is built in the factory to control fiber bending, so no field work is applied to the fiber bending at this hinge point. Specifically, the chassis hinge 324 and cable routing hardware are designed to ensure that the manufacturer recommended bend radius is not violated when the chassis is opened or closed. For example, the chassis 322 can include a pigtail chassis 153A, B mounted so that the slack associated with the pigtail remains fixed when the chassis 322 moves in its operating range.

  Furthermore, the transition part 131 and the transition part storage area 133 can be arranged on the chassis 322. In this configuration, when the chassis 322 is in the open position, the transition unit 131 can be accessed from above. In order to ensure that the input fibers and pigtails are not disturbed or distorted by unacceptable methods, the enclosure 300 may be configured in the factory (or manufacturing facility) so that the cable bundles are placed around the hinges 324. It is configurable. The preconfiguration of the enclosure 300 reduces the possibility of miswiring.

  Specifically, preferred embodiments of the enclosure 301 include, for example, a top panel 302, a first side panel 304, a second side panel 306, a bottom panel 308, a back panel 309, a first door 310, and a second. A door 312 is included, which collectively constitute the external dimensions and structure of the enclosure 310. Furthermore, the enclosure 301 can include one or more transport handles 318 to facilitate the deployment of the enclosure 301 at a desired location. The first and second doors 310 and 312 are pivotably attachable by hinged edges 313, 315, respectively, to provide smooth access to components mounted inside the enclosure 301. Furthermore, the first and second doors 310 and 312 can smoothly provide tamper resistance and weather resistance by adopting the assembly of the lip 316 and the channel 314. Channel 314 can function in the context of an elastic gasket material to provide a smoother weatherproof seal. Enclosure 301 includes an upper surface 302, a first side surface 304, a second side surface 306, and a second side surface 306 to provide a smoother weatherproof seal when the first and second doors 312, 314 are closed. A protrusion 307 extending along the interior of the bottom surface 308 can further be included. By installing the lock 311 in the door, unauthorized access to the internal volume of the enclosure 301 can be prevented.

  Enclosure 301 includes a swing frame 322 that is hinged along the sides using hinges 324. The hinge 324 allows the frame 322 to pivot such that the opposite side of the hinge 324 moves away from the interior volume of the enclosure 301. As shown in FIG. 10, when the frame 322 is in the open position, the rear feedthrough 320 can be accessed along with the cable management tray 328, the splitter chassis rear carver 330, and the rear termination connection 332. is there.

  In contrast, only the components on the front bulkhead 335 are easily accessible when the swing frame 322 is in the closed position. When the swing frame 322 is in the closed position, for example, the termination field bulkhead 334 and the splitter chassis bulkhead 336 are accessible.

  The trend towards relatively high capacity fiber distribution hubs can create further concerns regarding back access to optical components and cables. Increasing the width of the chassis, along with other dimensions of the enclosure, would have to accommodate an increased termination capacity including an increased number of connectors, splitter modules, junctions, and / or fiber jumpers. In addition to the problems described in connection with the swing frame chassis of FIG. 10, further problems can occur as the width of the swing frame FDH chassis 322 increases.

  As the width of the swing frame chassis 322 increases, the width of the cabinet must be increased proportionally to accommodate the clearance between the swing frame chassis and the side walls of the enclosure when the chassis swings open. Don't be. When a swing frame chassis is used in the interior, particularly when installed on a utility pole, the width of the entire cabinet is larger than the conventional allowable width at a specific point. For example, the chassis width needs to be increased to accommodate a larger termination field, but the size of the swing frame chassis is proportionally increased due to the addition of a larger width to the enclosure to accommodate the swing frame. That would be unacceptable.

  FIG. 11A illustrates one embodiment of a fiber distribution hub 383 that has the ability to accommodate a large termination field and associated large swing frame while minimizing the additional enclosure width required to accommodate the swing frame chassis 322. ing. The hub 383 can be an enclosure and can include, for example, a rear enclosure portion 387, a front enclosure portion 385, a seam 381, and one or more access door panels 389A, 389B. The hub 383 includes a first access door 389A and a second access door 389B as shown. The hub 383 includes a split enclosure designed to have a seam 381 that extends substantially along the entire side, top, and bottom walls. The seam 381 provides a smooth separation of the front section 385 from the back section 387. The seam 381 substantially divides the entire enclosure, thus providing a reduction in the overall width of the enclosure necessary to accommodate the swing frame chassis 322 implementation. Enclosure implementations that do not utilize seams 381 will require additional width to allow clearance between the swing frame chassis and the sides of the enclosure. The split enclosure implementation of FIG. 11A is realized using a reinforced back section 387 that functions as a fixed structural member of the enclosure. The seam 381 is sufficient relative to the back section 387 by dividing the enclosure in position along the depth to ensure structural integrity of the entire chassis via the back section 387 and the reinforced hinge 391. Provides side wall rigidity.

  Since FDH is typically an environmental enclosure, it must be protected against water and other environmental factors by sealing the seam 381 within the enclosure. Thus, the rear enclosure portion 387, the front enclosure section 385, and the chassis are joined by compression sealing through a seam 381 that functions as an environmental barrier. Hinge 391 is located outside of seam 381 so that continuous sealing can be routed around the enclosure to achieve environmental sealing. Furthermore, the entire back section 387 of the enclosure can be covered by a rain shield 393 that functions as the roof of the enclosure containing the split sections. The hinge 391 is designed and configured to manage the bend radius of the fiber in an acceptable manner.

  Further, the front enclosure portion 385 and the back enclosure portion 387 are joined by two quick release latches that are disposed within the enclosure and accessible only through the front door. These latches actuate a release action that provides access to the enclosure by allowing separation of the chassis section in a direction away from the rear enclosure portion 378. These latches provide environmental sealing by pulling the enclosure back and providing compression against the seam 381. The FDH 383 can further comprise an angled cable outlet channel for removing moisture from the cable seal. If employed, this slanted outlet is associated with the rear section of the enclosure.

  The back enclosure portion 387 can provide a back and / or side plug by providing a unique cable management scheme. The rear plug is provided through a tilted fixture in much the same way as a conventional enclosure to remove moisture from the cable ceiling. Also, the rear section of the split enclosure is designed to be large enough to allow cable insertion from the side into the enclosure by allowing the side sections to accept the same fixture.

  11B-11G further illustrate an example of a split enclosure. FIG. 11B shows a plan view of the enclosure 440 showing the top surface 442 composed of rain shields 446. FIG. 11C shows a view having a back surface 444 and utility pole mounting brackets 445A-D. FIG. 11D shows the side of the enclosure showing the rain shield 446, the front portion 448, the central portion 447, and the back portion 444. In the embodiment of FIG. 11D, the back portion 444 will remain fixed, for example, by being supported on a utility pole. The central portion 447 is pivotally attached to the back portion using a hinge and the front portion 448 is pivotally attached to the central portion 447 using the hinge 450. FIG. 11E shows a front view of an enclosure 441 having, for example, an optical splitter mounting area 456, a subscriber termination field 458, a cable raceway 454, and a first door 452A and a second door 452B. FIG. 11F shows an enclosure 459 with a back portion 444 and a gasket 450 pivotally mounted to the central portion 447. The central portion 447 is in an open position and is disengaged from the back portion, for example, along three edges. The enclosure 459 can further include a shelf 460, an optical splitter module mounting area, a subscriber field, and the like. FIG. 11G shows a perspective view showing the back surface portion of the enclosure 459. The latch 464 holds the central portion 447 in the closed position.

  FIGS. 11H and 11I illustrate an exemplary method of working together with an embodiment of an FDH enclosure that utilizes one or more swing chassis. First, a determination is made as to whether the enclosure uses the swing chassis 322 (step 337). If the swing chassis is not being used, the enclosure is accessed using conventional techniques known in the art (stage 339). If the swing chassis 322 is identified in step 337, a determination is made as to whether the enclosure is a split enclosure (step 341). If the enclosure is not a split enclosure, the enclosure door is opened (step 343) and the method flow proceeds to the input of step 351. In contrast, if a split enclosure is identified in step 341, the enclosure door is opened (step 345) and then one or more compression latches are released (step 347).

  The use of a compression latch keeps the enclosure gasket in a compressed state to provide smooth weathering. After releasing the compression latch, the movable portion of the enclosure is moved to its open position (step 349). For example, the first section 448 and / or the central section 447 can be pivoted to an open position. After step 349, the method flow from the “No” path of step 341 is rejoining the main method flow. The swing chassis 322 is unlatched (step 351), and the chassis is pivoted to the open position (step 353).

  After the chassis is in the open position, a determination is made as to whether the chassis frame has a locking mechanism to maintain the frame at a desired angle relative to the enclosure (stage 355).

  If the locking mechanism is not present, the method flow will proceed to input at step 359. In contrast, if a locking mechanism is present, engaging the lock will hold the open chassis in place (step 357). The desired service is then executed (step 359). As an example, the desired service may include repairing damaged or worn components in the enclosure, inspecting components in the enclosure, connecting subscribers, disconnecting subscribers, adding additional components such as optical splitter modules to the enclosure, and Alternatively, removal of components from the enclosure can be included.

  Next, referring to FIG. 11I, after executing the service, a determination is made as to whether the chassis frame is locked in the open position (step 361). If the chassis is not locked in the open position, the method flow will proceed to input at step 365. In contrast, if the frame is locked open, the lock is released (step 363). The chassis is then closed (stage 365) and latched in the closed position (stage 367).

  A determination is then made as to whether the split enclosure is in the open position (step 369). If the split enclosure is not in use, the method flow will proceed to the input of step 375. In contrast, if a split enclosure is used and open, the appropriate enclosure section is closed (stage 371) and the compression latch is engaged (stage 373). The enclosure door is then closed (step 375) and locked if necessary.

  FDH enclosures are typically attached to utility poles at high locations that are inaccessible to track technicians standing on the ground, and track technicians therefore typically access the enclosure by climbing to the height of the enclosure. is doing. Often, the enclosure allows utility engineers or balconies (which are essentially permanent fixtures attached to utility poles below the enclosure) to allow track engineers to stand in front of the enclosure when performing line connections; It is installed in relation to. Track maintenance technicians can climb the height of the balcony by ladders or stairs and then move to the balcony to perform work. In the standard safety procedures used in the art, track maintenance technicians, when climbing the ladder and moving to the balcony, latch into the appropriate safety mechanism in the context of the safety harness, Or, when working on the platform, it is required to prevent falling if it falls. Safety latching and access facilities are typically provided with the installation of enclosures such as FDH installations.

  Enclosures made to be used in copper equipment installations such as POTS (Plain Old Telephone System) installations are typically made from heavy gauge steel and therefore to latch the safety harness directly to the enclosure Sufficient strength was provided. However, new enclosures are constructed from aluminum or other lightweight corrosion resistant materials to provide the element with relatively easy installation and additional protection against long term exposure. These lightweight enclosures do not provide sufficient structural strength to reliably prevent falling when a lifeline is attached.

  In normal field work, track engineers will move from the ladder to the platform or balcony and begin work on the elevated enclosure. The safety procedure stipulates that track maintenance engineers first attach the lifeline to the appropriate structure of the utility pole (in this specification, the latch point) before moving. Facilitates the attachment of lifelines to latch points that are easily accessible and optimally placed in relation to track technicians on the ladder. In addition, the latch point provides the track technician with the necessary mobility as the track technician moves from the ladder to the platform and when working with the enclosure. It is also possible to provide a structural handle. The structural handle can be configured to support the tracker's weight as the tracker moves from the ladder to the platform. Furthermore, the handle can be configured to withstand loads associated with dropping. Latch points and handles are attached to both sides of the utility pole and attached enclosure, since it cannot be reliably determined in advance from which side of the utility pole the track technician will climb the platform.

  The preferred embodiment of the elevated FDH includes a latch point associated with a structural member that can be installed as an option with a utility pole mounted FDH. By using this optional member, an FDH with a latch point can be installed only in the desired situation. If a latch point is not required, the FDH will be provided with a standard mounting bracket. Yet another embodiment of an elevated FDH provides a standard mounting bracket that is expandable after installation by adding structural members and latch points, if desired, after the initial installation of the FDH. . Latch points and / or structural members are used to prevent falls and / or can be damaged when used beyond normal operating ranges, so in the embodiment of an elevated FDH, Latch points and / or structural members that can be exchanged are utilized.

  FIG. 12A shows a preferred embodiment of an elevated FDH 399 attached to a utility pole 401 using a structural member 404 with a latch point 400. The FDH 399 can include an enclosure 403, a structural member 404, a mounting bracket 410, and a lower mounting bracket 412. The structural member 404 can function as a stabilizing member and / or a mounting bracket that can optionally include a latch point 400 attached to the structural member 404. Furthermore, the handle 406 can be detachably attached to the enclosure mounting bracket 410 using the bolt 408. The structural member 404 can be constructed from, for example, a steel beam such as a welded beam, and the fall load due to an accident can be directly applied to the utility pole 401 without depending on the strength of the elevated FDH enclosure 403. It is possible to provide sufficient strength for transmission. In the preferred embodiment, the structural member 404 can extend substantially across the width of the enclosure 403. Furthermore, the latch point 400 is arranged so that trackers can access the FDH from the front, side, and / or back of the FDH399. Furthermore, the latch point 400 is arranged so that a track technician can hang the lifeline on the doors 414, 416 of the FDH 399 while working in the enclosure 403. In the preferred embodiment of the structural member 404, steel is used, but other materials such as aluminum, titanium, and / or composite materials can be used for the beam, if desired. In order to achieve a predetermined load bearing capacity, the cross-sectional dimensions of the material can be appropriately changed for a particular material. The implementation of FDH399 can utilize a structural member 404 having a shape other than that shown in FIG. 12A. The structural member 404 can be directly attached to the electric pole 401 or can be attached to an interposition structure attached to the electric pole 401. Furthermore, the stabilizer bar 404 can be removed as necessary.

  In the embodiment of FIG. 12A, the latch point can, for example, secure a standard track technician's safety harness and further provide sufficient strength to hold the track technician in the event of an accidental fall. It consists of a safety ring 400 made from a structurally durable “D-ring” loop that is sized accordingly. The latch point 400 can be exchanged and can be defined to be exchanged after being dropped once. As a result, the latch point 400 is designed so that it can be easily replaced in the context of the bracket 402 using fasteners such as bolts 401. In the illustrated embodiment, a handle 406 is also provided. By fixing the handle 406 to the side of the utility pole mounting bracket, it is possible to smoothly perform the movement of the track maintenance technician from the ladder to the platform. Specifically, the handle 406 can be attached to the flange 410 on the structural member 404 and is arranged to assist the track maintenance engineer during movement from the ladder to the utility pole 401. For example, a trackline technician who climbs the utility pole 401 latches the safety harness against the latch point 400 and then holds the handle 406 when moving from the ladder to a safe location on the balcony in front of the elevated FDH enclosure. Will do.

  A typical installation of an elevated FDH 399 would include a latch point 400 and a handle 406 attached to either side of the FDH 399. Since the handle 406 is not adapted to the load of dropping due to an accident, the handle 406 is designed not to accept a latch from the safety harness of the track maintenance engineer. Is possible. This safety-related function keeps the handle diameter within an acceptable range for a general track technician to grip, while surpassing the diameter that works by the track latch's harness safety latch. This is realized by increasing the diameter of the handle 406. As a result, the track maintenance technician is forced to connect the safety latch of the harness only to devices that are suitable for dropping, such as the latch point 400.

  FIG. 12B illustrates an exemplary method of using an elevated FDH enclosure 399 with a handle 406 and a latch point 400. The method of FIG. 12B begins when the track maintenance technician places the ladder relative to the utility pole 401 to which the elevated FDH 399 is attached (step 420). Track maintenance technicians are climbing the utility pole to the height of the balcony associated with the elevated FDH399 (stage 422). The track technician then attaches a lifeline adapted to prevent the fall to the latch point 400 (step 424). The track technician then grips the handle 406 and moves from the ladder to the balcony (stage 426).

  On the balcony, track engineers have opened doors 414 and 416 to access components located within the interior volume of the elevated FDH 399 (stage 428). Perform any necessary services (step 430) and then close the doors 414, 416 (step 432). The track maintenance technician then grips the handle 406 and moves to the ladder (step 434). The lifeline is removed from the latch point 400 (step 436) and the track maintenance technician is descending the ladder (step 438).

  FIG. 13 is a flowchart illustrating a method for installing and connecting a pigtail of an optical splitter module according to a preferred embodiment of the present invention. The method includes installing 522 a splitter module having an output pigtail in the patch panel position. Furthermore, the method includes a step 524 of routing the output pigtail of the splitter module circumferentially around the subscriber termination field. The method includes a step 526 of connecting the connector end of each splitter pigtail to the splitter module storage container. These storage containers are initially preconditionable at the factory. The method includes a next step 528 of preserving pigtail slack in half loops in adjacent vertical channels. Further, the method includes a step 530 of determining whether to connect or disconnect the service order. If a service order needs to be connected, the method includes a determination at step 532 as to whether a splitter output is available to assign. If it is determined that the splitter output is available for assignment, the method proceeds to stage 542 of disengaging the connector-attached pigtail from the storage position. If it is determined at step 538 that the splitter output is not available, a determination is made as to whether the location is available to add modules. If yes, the method steps are repeated again starting at step 522. However, if it is determined that there is no usable position, the maximum module capacity of the system has been reached.

  The method also includes the option of cutting the service order at step 530. Stage 534 includes disengaging the connector-attached pigtail from the subscriber position, and stage 536 includes routing the pigtail through an extended circumferential path around the subscriber termination field. Contains.

  The method further includes connecting 544 a splitter pigtail to the subscriber location and routing 546 the pigtail through a reduced circumferential path around the subscriber termination field. The method includes a step 548 of preserving pigtail slack in a tuned half loop in an adjacent vertical channel.

  Alternative embodiments of the internal components of the FDH can be implemented according to the disclosure herein. As an example, a hinged storage panel can be used to store unused pigtails. FIG. 14A shows a chassis 600 that utilizes hinged storage. The embodiment of FIG. 14A, for example, allows the chassis frame 602, module holder 603, splitter module mounting area 604, upper splitter module shelf 605, chassis frame 602, and storage / storage panel 612 to pivot relative to the interior surface of the enclosure. Mounting bracket 606, internal volume 608, storage panel hinge 610, storage storage panel 612, storage section with multiple containers 614, fiber pigtail guide 616, fiber pigtail panel 618, storage panel primary guide 620, and chassis fiber A guide 622 can be included.

  Chassis frame 602 includes an internal volume 608 that houses a subscriber termination field. Chassis 602 also includes a splitter module shelf 605 for supporting the splitter module above the subscriber termination field. The splitter module is held in place using a holder 603. The cage 603 may be a thumbscrew, for example. A fiber pigtail with a connectorized end is fitted with a chassis cable guide 622, a panel primary guide 620, and one or more panels before being stored in the storage container field 614 via the pigtail connector. Routed through a fiber pigtail guide 616.

  The hinged storage / storage panel 612 can provide higher fiber connector density compared to embodiments that utilize a splitter module with storage containers on an optical splitter faceplate or the like. Also, the hinged storage / storage panel 612 can provide a higher fiber connector density compared to embodiments utilizing a splitter module located below the subscriber termination field. Furthermore, the storage containers 614 can be organized as rows of 16 or 32 containers to accommodate splitter modules with 16 or 32 pigtails. As the pigtail connector is removed from the storage container 614 and deployed in the subscriber termination field, the container row can be removed from the hinge coupling panel 612 and reused elsewhere in the FDH. Furthermore, if all pigtails are deployed in the subscriber termination field, the entire hinged panel 612 can be removed, thereby providing unobstructed access to the subscriber termination field. Furthermore, the hinged panel 612 can be sized as a protective cover for the subscriber termination field. If gaskets or other removable sealing means are provided, the hinged panel 612 can function to prevent dust and dirt from accumulating on the subscriber termination field.

  The optical fiber 1712 associated with the removed connector 1708 can be removed from the fiber channel 1510 (stage 2010). By routing optical fiber 1712 through one or more fiber channels 1510 in the enclosure, excess fiber management can be accommodated (step 2012). The adapter dust cap 1706 can be removed from the subscriber termination in the subscriber termination field (step 2014). The connector 1708 removed from the storage adapter 1600 can be connected to the subscriber end from which the adapter dust cap 1706 has been removed (step 2016). When connector 1708 is plugged into a subscriber termination, communication services can be provided to the subscriber associated with that termination. The adapter dust cap 1706 removed from the subscriber end in step 2014 can be inserted into the storage adapter 1600 from which the connector 1708 was removed in step 2004 (step 2018).
