Abstract

A fiber optic distribution system provides a frame having several bays for receiving connector modules, associated jumper organizers, and upper and lower troughs for conveying jumper fibers between adjacent bays. The jumper organizers are constructed such that interbay jumpers need not undergo more than two continuous bends of 90 DEG , and further easily store excess jumper slack, such as is required to avoid modal noise, even when both ends of the jumper are terminated in the same tray or cabinet. Each connector module has a plurality of connector trays pivotally attached to a cabinet using a swivel bracket which is located adjacent a gap in the tray sidewall; this allows placement of the incoming fibers into the tray without the need for threading the fibers through a hole, and also minimizes fiber stress during pivoting movement of the trays. Front and back plane storage areas are provided for receiving excess slack from both incoming and jumper fibers, and a passageway may join these areas to allow customized fiber circuit paths on the tray. Boot biasing ribs are provided on the tray, along with radius limiting ribs, to maintain a proper bend radius of the jumper fibers as they exit the tray. A novel coupling adapter is also provided which flips one end of the interconnection device upward to allow easier installation of a connector plug.

Description

Fiber distribution frame system
The background of invention
1. FIELD OF THE INVENTION
The present invention relates generally to be used for the coupling arrangement of cable, and relating in particular to a kind of fibre-optic distribution frame that in telecommunications, is used for cross connection and interconnection, described device provides the storage of jumper cable and the fiber on a given pallet and the improvement control of interconnection.
2. the explanation of prior art
In the past for many years in, light transmitting fiber has become the comparatively ideal medium that is used to transmit communication signal above copper conductor, because opposite with copper conductor, especially because crooked or may produce the loss of signal when being damaged on the contrary at light transmitting fiber, cable management and fibre-optic control are completely different.Designed and be used for fibre-optic distributor so that this loss is reduced to minimum degree.For example, United States Patent (USP) the 5th, 093, a kind of have a front panel and a plurality of chamber that skids off the front shelf have been disclosed for No. 887, each described shelf supporting one or more splicing pallet, and (the splicing pallet can also pass through from the rear panel of framework, as at United States Patent (USP) the 5th, 241, illustrated in No. 617).The fiber that enters and export is passed in the breach that forms on rear wall, diapire or the roof of chamber.Wire clamp is used to a suitable minimum bending radius fiber clamp is held on the pallet, and a supporting arm that pivots uses with each shelf, also makes the bending stress to fiber be reduced to minimum degree.
At United States Patent (USP) the 4th, 792, in No. 203, the storage pallet of installing along the left and right sides medial surface of chamber pivots outwardly by preceding plane of inlet.Described pallet is designed to be the path that can have separately, is used for storage from three fiber interconnections, promptly the relaying fiber, draw (or cross-over connection) fiber and distribute the loose part of fiber.Described relaying fiber and distribution fiber are drawn by the breach that forms on the sidewall of chamber.
United States Patent (USP) the 5th, 067,784 have disclosed a kind of similar design, and in this design, pallet also is to install along the left and right sides medial surface of chamber, but they are to skid off rather than pivot.Device helps jumper cable and crosses pallet on other side from the pallet on a side of chamber.Loose part in the surplus of bonding line can allow to be suspended on the middle section of chamber.Each pallet has an installation region that is used to hold several optical fiber junctions to interconnection or dividing plate and in a zone of the too much loose part that is used to preserve the fiber of drawing from the pallet rear portion of described dividing plate back.Topped this back region of hinged plate.Draw pallet on the arc extension of the fiber corner before being positioned at pallet that is connected previously with dividing plate.Camber blades are used to limit the minimum bending radius that fiber stands 90 ° of bendings from described dividing plate to described arc extension.
A kind of similar splice tray is at United States Patent (USP) the 5th, 071, illustrated in 211.Then in the sort of structure, the foremost part of pallet is hinged and can moves downward inlet with the previous section that helps to lead to dividing plate.
At United States Patent (USP) the 4th, 824, the another kind of light transmitting fiber distributor that has illustrated in 196 has a plurality of module or drawers that are pivotably mounted on the inside of a chamber.One has several pages less hinged pallet separately and can be connected with drawer in the back of dividing plate.Dividing plate can have stairway step shape or zigzag shape, and therefore the fiber of drawing forward just needn't stand big angle of bend and can also make the width of drawer less.The foremost part of drawer forms a door of downward hinge through again.
As at United States Patent (USP) the 5th, 247, in 603 further disclose like that, described pallet can be designed for cross connection (use jumper) or interconnection (not having jumper).The structure that is disclosed is with a kind of page of arranged pallet, and wherein each pallet can be maintained on one of three via positions.This patent discussion with quote many pieces of general other lists of references relevant with distributor and splice tray.
When aforementioned design was some aspects at fibre optics cable control, these designs had been proved to be the required standard progressively that is not suitable for these devices.For example, these designs must be able to adapt to up to the transfer rate of 2 gilberts (Gb) acceptable very little rate error.The length that also will believe the cross-over connection fiber should be more than 2 meters or 2 meters at present so that the highest noise of the frequency of occurrences is reduced to minimum degree.In existing distributor, the excess electron excess fraction loose from the jumper cable of this length just must be wound on various pillars and the wall too much, thereby trends towards bonding or make fiber more be difficult to handle on the other hand.These devices are not suitably at the management of the very long bonding line that is used for following occasion: (1) is all in the interconnection of a pair of fiber of same drawer or indoor termination; But the (ii) interconnection of a pair of fiber, its two ends are in different indoor terminations on the same framed bent in distribution frame, or the (iii) interconnection of a pair of fiber, and its two ends stop in the different framed bents of the distribution frame of framed bent more than.
Except that incompatibility aspect the jumper cable control, the distributor of prior art can also adopt in given drawer or the storage of the fiber on the pallet and the improvement structure of interconnection.For example, at United States Patent (USP) the 5th, 067, in the structure shown in No. 78, when blade is used to overcome pulling force and keeps the radius of fiber, if joint has the sleeve pipe or the clip of an extension, the then dorsal part of blade and the serious bending that in fact can produce fiber.Several traditional jointings have this class sleeve pipe, and these sleeve pipes from first to last contact to the dorsal surface extension of blade and with described dorsal surface, thereby cause that the trace in fiber is crooked.Really, illustrated design (Figure 23) is compared to have disclosed for the front that makes pallet and is held long sleeve pipe in this design and the United States Patent (USP) the 5th, 071,211, just must remove blade fully, but still also exist the foremost wall of fiber contact pallet and the excessive bending that produces.Therefore wish a kind of light transmitting fiber distributor of invention, this distributor can be controlled at the minimum bending radius of the fiber of storing and interconnecting on the given pallet more satisfactoryly, and no matter superfluous jumper cable is a kind of cable indoor or that framed bent is interior or the framed bent centre, and this distributor can both be controlled superfluous jumper cable suitably.It also helps provides a kind of structure that can allow to lead to by the front panel of chamber the back side, back inlet.
Summary of the invention
The invention provides a kind of fiber distribution frame system, it comprises: at least one is arranged on a main framed bent that distributes on the frame, described framed bent comprises one or more chamber, each chamber have a plurality of splice tray and, optional one or more are used for the auxiliary tray of articulated joint, male part, separation member etc.Each framed bent also comprises a plurality of bonding line assemblys (organizer) and be used for carrying the upper and lower delivery chute of bonding line fiber between the framed bent of the distribution frame of framed bent more than.This device is just considered like this two kinds of the interconnection of fiber and cross connections.Each bonding line assembly has a line tube that is used to support or guide the bonding line fiber, and the control of very long fiber is considered in its general layout, thereby any fiber is subjected at the most two greater than 90 ° bending, and these one or two be bent to and mostly be 180 °, make by the loss of signal of bonding line and reduce to minimum degree thereby reduce stress on fiber thus.The use of many line tubes has been cancelled and need so just have been avoided the crooked of fiber and generally help to seek and handle a single fiber along the needs of the loose part of fiber of the too much coiling of any one line tube.
Described joint drawer is installed on the chamber pivotly and is provided with and makes them remain on storage and entry position and make fiber bending reduce to the device of minimum degree in the drawer motion process.Each drawer also is designed to be by providing one to be used to introduce loose storage area of fiber and to keep the least radius of output fiber to remain on the least radius on several fibers with blade or wall.The present invention uses a double-walled rib to be displaced on the surface of least radius so that the decline with the output fiber additionally to be provided; It is particularly useful when this bias voltage surface joint on drawing fiber ends has one to extend sleeve pipe.Loose storage area can be provided with frontal plane and back plane, so that provide interconnection capability on the lap of loose storage area.

The explanation of preferred embodiment
Referring now to accompanying drawing, especially with reference to Fig. 1, light transmitting fiber distributor of the present invention embodiment 10 shown in the figure.Distributor 10 generally comprises a framework 12 that constitutes a framed bent, it has a plurality of connector modules 14 that are connected with framework 12 and a plurality of bonding line subassembly 16 that is provided with adjacent to the connector module in described framed bent, bonding line subassembly 16 is generally vertically arranged when upright with convenient framework 12.Connector module 14 is also vertically being piled up, and described device can also comprise two delivery chutes 18 and 20 on the upper and lower end that is separately positioned on framework 12.As following further discussion, framework 12 can comprise a traditional equipment rack made from steel part.
Now please refer to Fig. 2, each connector module 14 is made up of chamber of joint drawer that has a plurality of portions that set within it or pallet 24 or housing 22.Chamber 22 can be made with any durable material, and more satisfactory be to make by crooked metal sheet.More satisfactory is that a front panel 26 of preprinting content transparent (polymerization) and helpful identification pallet can be connected with the initial perforate of chamber 22.Pallet 24 (further detailed icon in Fig. 3 and 4) has a front area 28 that holds a plurality of fiber interconnection devices 30 and a Background Region 32 that is used to store from the loose part of input fiber 34.Pallet 24 be installed on chamber 22 with a kind of articulated manner so that described pallet can from one fully a restoration position in chamber 22 (Fig. 4) be pivoted to a pallet entry position only exposing interconnect area 28 and further be pivoted to the back side entrance location that enters loose storage area 32, thereby further obtain the path that leads to 22 inside, chamber.Pallet is more satisfactory to be to pivot along common line, and for example pin or the screw 36 that is passed in turret 38 on each pallet 24 by use pivots.Device can be set to pallet is fixed on two positions of first releasedly, and for example intermediate plate 40 is installed on the edge near each pallet of back restoration position 32.Intermediate plate 40 has a little bend so that any one stable being press-fitted with two clasps 42 and 44 to be provided, and the former (intermediate plate) is installed on a rear wall of chamber 22, and latter's (clasp) is installed near the sidewall of the chamber 22 the initial perforate of chamber 22.
Be fixed on input fiber 34 on the back side of framework 12 with a cable grip 46 that is installed on chamber mount pad 48 by 50 inlet chambers 22 of the perforate on another sidewall of chamber 22 and be passed in a opening 52 on the sidewall of pallet and further enter in the given pallet 24.Hope can provide a wide as far as possible opening, because it helps the installation on the spot of the fibre optics cable of brachymemma in advance, does not promptly need the cable of brachymemma is in advance passed little hole.One clip 54 with polyfoam compresses fiber and provides strain relief to fiber during around pin 36 pivots when pallet.One polyfoam folder 54 can connect with the fibrous face of 250 microns, 900 microns or 3 millimeters, or spiral wound or go out pipe.Excessive loose part from fiber is wound onto on the minimum bending radius wall 56 of loose part storage area 32, and described loose part storage area can also be provided with several helping fiber is remained on claw or little teat 57 in the pallet.The end of fiber 34 is drawn towards interconnect area 28, and is connected with an optical fiber junction usually, a hoop type joint 58 that for example uses a common socket or male part 62 and the joint 60 identical with to match.A plurality of such interconnection devices 30 illustrate in Fig. 3 abreast.A device 30a illustrates a position of raising slightly that helps joint 60a to be connected with male part 62a.Although these characteristics can use multitude of different ways (with reference to United States Patent (USP) the 4th, 986, No. 762) to realize, disclose a kind of structure of novelty at this, it can provide a kind of firm connection of further height opposing side direction pulling force.This structure is shown in Figure 5.
The inlet through strengthening that leads to joint 60a is by adopting a strip socket 64 that at one end is pivotally secured in pallet 24 on 66 to realize.In this preferred embodiment, pivotable (installation) be by provide one on end 66 be installed in and omit above a cantilever 70 of pallet 24 base plates combine the axle or pivotal axis realize.Arm 70 can be by being stamped to form it from the sheet metal that forms pallet 24 base plates.Male part 62 is installed on the other end 72 of socket 64, and this is except around the rotation of its pivot, owing to be lifted to male part on the tray substrate thereby also strengthened leading to the inlet of male part.Device also provides the device that socket 64 is fixed in releasedly two positions, two positions promptly, operating position that the alignment axis of male part 62a parallels with the backplate surface of pallet substantially and axis become a retracted position of oblique with respect to base plate.Two handles or the handgrip 74 that stretch out pivot 68 from the end 66 of socket 64 have the projection of inside sensing, and these projections form a frictional fit with the projection of outside sensing on cantilever 70.By this way, be to be on the projection of arm 70 as the projection of carpopodium 74, socket 64 will be displaced to described operating position, but is lower than the projection of arm 70 as the projection of carpopodium 74, and then socket 64 will be displaced to retracted position.Described handle makes progress with respect to the length of socket 64 and slight curvingly their projection is just placed on the arm 64 when being on the operating position with box lunch.
Stability and anti-side direction pulling force are to realize by being provided for the base plate that a end 72 with socket 64 is fixed in pallet 24 releasedly in addition.In this illustrated embodiment, this is by forming protuberance or ridge 76 and by providing an end 72 that has claw piece 80 to realize on the either side in the hole 78 that forms on the base plate of pallet 24, described claw engaging hole 78 and ridge 76 releasedly when socket is in operating position.Because an end of this structure fixed installation male part, this structure can help more firmly to keep socket.When socket 64 from retracted position when operating position moves, when crossing projection on the arm 70, the projection on handle 74 can hear and feel crepitation for the first time, and, can hear and feel crepitation for the second time when further exerting pressure and during latch spare 80 engagement ridge 76.
Please see Figure 3 again, Fig. 4 especially, pallet 24 also is provided with and is used for making the device that keeps its minimum bending radius at the fiber of interconnect area 28, that is, and a plurality of double-walled ribs 82 that are installed on the base plate of pallet 24 or integrally constitute with it.It is a pair of surperficial 84 and 86 that adjacent rib 82 forms, and they are respectively applied for a fiber is remained on the minimum bending radius towards a minimum bending radius bias voltage or with a fiber.For example, show to have a long strain relief sleeve pipe 90 among a fiber connector 88 figure.In traditional splice tray, the crooked tension force of sleeve pipe 90 opposing fibers, thereby the fiber bending of violent (seriously) just can just produce outside sleeve pipe.Though this restriction can be overcome by widening pallet, general hope is to keep pallet compact as much as possible.The surface 84 is used to contact long sleeve pipe and they is offset to minimum bending radius, so that fiber need not live through many bendings just exceeding sleeve pipe, thereby makes pallet keep comparatively compact structure.Surface 86 is used to keep having the minimum bending radius than a joint 92 of short sleeve 94.The fiber of interconnection is left away pallet to make fibre stress be reduced to Min. at crossover ports 96 places near turret 38 in the tray motion process.
With further reference to Fig. 6, a given chamber 22 can be fixed with the one or more auxiliary tray 24 ' that is very similar to splice tray 24.Different auxiliary trays can be different purposes, for example, and for the storage of the loose part of fiber of surplus is provided with.Illustrated auxiliary tray 24 ' is designed for hinge joint (splicing) storage, and it has a twist joint zone 98 that is used to hold (strand) joint 100 of a plurality of discrete fibres, and described (strand) joint 100 is used for being interconnected to the fiber of feeding/distribute with drawing fiber.Term " hinge joint " is often referred to a kind of interconnection device that is used for permanent use, and " joint " typically refers to the device of a kind of detachably and again tangle (remat-able).Yet; the person skilled in the art is understood that these terms should not be on the limited significance for the present invention and makes an explanation, because the present invention for required protection can be applicable to have distributor and the splice tray that is used for fibre-optic permanent and interim two kinds of devices of interconnection.The present invention also can use other interconnection device, for example male part, separation vessel etc.
Although distributor of the present invention can be used for the fibre optics cable in single framed bent is interconnected to remote control equipment, but it similarly can be used in the cross-coupled application, the cross-over connection fiber is to carry between different framed bents in these are used, as shown in Figure 7.Each bonding line subassembly 16 comprises the line tube 102 of a minimum bending radius that is used to keep the loose part of bonding line and is used for fiber is remained on one or more fixation fingers (retention raceway) 104 in the vertical wire pipeline of subassembly.A plurality of spools and upper and lower delivery chute are set in each framed bent can allow to support jumper cable, and such two bendings are limited in about 180 ° not exist more than two a kind of like this modes greater than 90 ° continuous bend.Storage also is easy from the loose part 106 of the too much bonding line of the cross connection that terminates in bonding line two ends in same chamber or the pallet; For making the highest noise of the frequency of occurrences be reduced to minimum degree, so too much loose part may be needed.
The present invention also provides the least interference of other fiber or does not have any interference of other fiber when settling or reset bonding line, and keeps the minimum bending radius of 1.5 inches (3.8 centimetres) in whole device.
According to the size change widely of the various different parts of desired use distributor 10, as mentioned above, described device can advantageously be designed to be suitable on the frame of installation code equipment.These frames have wide framework of about 7 feet high and 23 inches (58 centimetres) or framed bent.Following approx. dimension is to determine according to the use of this framed bent.Chamber 22 is 17 inches * 12 inches * 5.2 inches, and the width that is used for the vertical wire pipe of bonding line assembly 16 is 6.5 inches.The chamber of 12 this sizes can vertically be joined and is stacked in the single framed bent.The pallet that is fitted in such chamber interior can hold 12 traditional hoop type joints, has 6 such pallets a chamber interior, is that the interconnection density of 864 joints is realized by aforesaid design and produce up to each framed bent.
Another embodiment 110 of fiber-distribution apparatus of the present invention is shown in Fig. 8 to 13.Distributor 110 has those parts that are similar in the device 10, comprises a framework 112, a plurality of different connector module 114, a plurality of bonding line subassembly 116 and delivery chute 118 and 120 up and down.As shown in Figure 9, connector module 114 has a chamber 122 higher than chamber 22, and splice tray 124 is remained on the position of a vertical storage.The carriage 126 of spiraltron that is used for fixing back plane is installed in 122 inside, chamber of splice tray back, and the radius of a plurality of rib 127 restriction back demifacet fibers.
Splice tray 124 and it in indoor motion shown in Figure 10 A to 10C.Splice tray 124 is also similar to pallet 24, and has an interconnect area 128, it be used to import fiber 134 the loose part of a back plane storage area 132 and be used for the loose part of a frontal plane storage area 133 of cross-over connection fiber 135.One common pivotal pin is passed in the turret 138 on each pallet 124.Pallet 124 has two latch folders 140 and 142 with single clasp 144 engagements in the preceding perforate of chamber 122; Described pallet can all be launched, as shown in Figure 11, and so that the inlet that leads to the back plane fiber to be provided.In addition, the loose part in forward and backward plane storage area closely is provided with mutually with the winding displacement again that allows forward and backward plane fibers and direct interconnection and can disturb interconnect area 128.Except the function of traditional cross connection and interconnection, by directly between the plane fibers of front and back, interface channel being set, distributor 110 provides usual circulation path to arrange, thus the application that allows the fiber plant of an in-line arrangement to be terminated on the spot and fiber is passed.
By other a plurality of walls or rib 146, they catch and guide fiber after fiber is drawn pallet by crossover ports, and fiber is being drawn the least radius that also keeps cross-over connection fiber 135 in pallet 124 and the motion process at pallet.When pallet 124 moved between restoration position and pallet entry position, rib 146 was to form on the plane that the direction of motion with cross-over connection fiber 135 intersects, and makes the bending radius at these two locational bonding lines be reduced to minimum degree thus.Rib 146 uses together with the loose part of frontal plane storage area, also makes each tie point break away from the external pull that puts on described cross-over connection fiber.If the cross-over connection fiber stands in Figure 12 a pulling force on the direction of big arrow, then most of tension force that produces just can dissipate by the coiling of the fiber in zone 133, so that in fact can feel very little tension force on interconnect area 128.The size of the various parts of distributor 110 also changes according to needed purposes, but it similarly will design to such an extent that can be fitted in the framed bent of a standard device.Following approximate size also is to determine according to the use of this framed bent.Chamber 122 is 17 inches * 12 inches * 15.7 inches, and the width that is used for the vertical wire pipe of bonding line assembly 116 is 5 inches.4 chambers of this size can vertically be joined and are stacked on the single framed bent.As device 10, device 110 can be used for directly interconnecting with remote control equipment, or is used in the distribution frame of many framed bents, as shown in Figure 13.
Though the present invention is illustrated with reference to specific embodiment this explanation does not mean it is to explain on a kind of limited significance.As long as with reference to explanation of the present invention, the various modifications of the embodiment that is disclosed and alternate embodiment of the present invention just will be conspicuous for the person skilled in the art.Therefore can conclude without prejudice to by spirit of the present invention that appended claims limited or can make this class under the situation of the scope of the invention that does not exceed claims and limited and revise.
