Specifically, what the invention proposes is a optical distributor consisting of a frame that includes the fiber organizer and the necessary means to store and guide fiber cables and cables inside.

The framework is the mechanical structure to which the cables are attached and it houses all the other elements of the delivery man.

The fiber organizer covers all media and characteristics used to guide and store fibers, rabillos fiber, splices, connectors and passive devices within a node at all points where they are not protected by the cable cover.

These elements will be installed in the exchanges or locations where fiber optic cable termination is necessary high capacity and the connection of optical fibers to equipment of transmission.

They can form a complete and isolated set that will allow the adjacent installation of several of them, both in wall as in rows, facing back, must have of the elements necessary for fixing to the top of the superstructure of the transmission room corresponding to the wall or floor, depending on its location.

Entering more into the configuration detail of the advocate, it must be said that this consists of a modular optical distribution set with 600 mm footprint that configured from a frame with doors made of sheet metal and polycarbonate type plastic that is configured as a suitable cabinet for indoor applications.

Within the aforementioned closet, there are three different areas, the fusion zone, or splice module equipped with 8 trays with 32 fusions each, the patch zone or module connection, consisting of 16 modules of 16 connectors, and the zone of hose management, or guidance and storage module for cords, equipped with system for reserve of over length type hangers

The outputs of the dealer are arranged as follows:

The external plant cables will undertake the delivery man or the top left when they come for channel or grid tray, or through the central area of the bottom when they come on technical ground.

The equipment hoses in all cases will come out from the top right of the dealer to be channeled directly to the gutters of
ceiling.

The assembly can be fixed by threaded stud to the ground or by fixing bars to the structures.

The splice module consists of a tray for holding trays, with capacity for 8 trays Up to 32 exit rails each or 16 trays with 16 rails each out; curvature limiters for the output of rabillos and guided to the upper area of patching; retention of plant cables in the lower right, the maximum number of Cables to retain is six.

The fusion trays are of the CAU type and for access them, swing down by pressing on the interlocking spring, leaving the tray in position Horizontal with easy accessibility.

This entire area will be protected from tampering. undue as well as possible accidental mechanical risks by using a door with lock system that closes the wardrobe.

The part of the dealer dedicated to patching plant cables to equipment or routing to other fibers, and that it has been called connection module, it is located in the part upper left and composed of 16 modules with capacity each of them for 18 adapters or terminations.

The 18 adapter module has an axis of pivot on its right side to access the connection part corresponding to the rabillos that come from the junction zone.

The fused rabillos go down the side left as they exit the termination modules, in separate mallets, individualizing module with splice tray, simplifying notably, the search for breakdowns in hoses

The area or module of the dealer for the guide function and storage of cords is included in the right of it. To manage the hoses and their over-lengths, devices of hanger storage in which excesses are hung, of so that for subsequent manipulations the identification of Cables can be made easily.

To reach any connection point of the 16 modules, the minimum length of hose we must have within the distributor is 5.5 meters which allows us to define the hose length more easily.

Thanks this dealer configuration is achieves a significant reduction in occupied space and a parity with the active elements of the plants, allowing interleave the active equipment and getting the dissipation of the heat they emit.

Given the above, it is found that the described optical distributor for telecommunications represents a innovative structure of structural features and constitutives unknown so far for that purpose, reasons that together with its practical utility, provide it with sufficient foundation to obtain the privilege of exclusivity that is requested.

-

Connection Modules (3)

-

Module of guidance and storage of cords (4).

The frame (1) is formed by a U-shaped envelope on which four blind doors (5) are mounted, thus being configured as a weapon.
River.

In the upper and lower part it has holes (6) and openings (7) for upper or lower access to the multi-fiber network cable distributor (as seen in fig. 8 and fig. 9). To hold them, next to each opening has three pairs of flanges or clamps. Likewise It has a second opening (7 ') in the upper right for the access of the monofiber cords coming from the equipment transmission (fig. 9).

In the upper frame socket (1), on the doors, has two or more small label holders (8) with a transparent plastic protector, which allows to insert in it a label (fig. 1 and fig. 2).

The space it occupies will be indicated on a label in the plant the dealer, and in the other the network and the functionality of the frame within it.

On the inside of some of the doors It has several large label holders (9) with a protector transparent plastic that allows to insert in them a cardboard or paper of an approximate size DIN A-4, in which the details relating to the fibers will be indicated installed and to the corresponding connections to the equipment (fig. 2).

On the inside of the other doors there is free space to incorporate adhesive labels indicating Wiring forms

In a preferred embodiment of the deliveryman, the described frame (1) has dimensions of 600 mm x 300 mm x 2,200 mm (Width x Depth x Height) (fig. 1), which covers the Side, bottom and doors. On this background the connection modules (3), splice (2) and cord storage (4) in three distinct areas.

The doors (5) are blind and 300 mm wide. width, with a total of four doors (fig. 1). Each of them It has a handle (14), and the lower left, which closes over the splice module area, it also has a lock (15) for triangle key. Inside the doors are they find a series of card holders and labels, according to what detailed above.

As noted, then, the dealer It consists of splice modules (2) and connection (3) which are left, as seen in figure 2, arranged in the left half of the frame (1), while the right half of said frame is occupied by the guide module and cord storage (4).

In the lower left third of the dealer the splice module (2) is available in which the splice trays (10).

This module consists of a guide removable (11) on which a support is attached or castile that houses up to 16 trays (10) of splice in the termination settings up to 256 f.o. (optical fibers). Said tray support is fixed to said removable guide and It consists of two symmetric elements on which the trays, allowing to be shot down from the vertical position (90º) (fig. 3) to the horizontal (0º) (fig. 4).

Under the trays a plate is arranged articulated and foldable (12), which allows the rest of the trays (10) on it in its working position, to give it greater solidity to the set (fig. 3).

In their resting position the trays are they are arranged vertically (fig. 3), fastened by a tape Velcro® type. In that position, the outer tray of the module splice is No. 1 and the inner tray No. 16. In position of work, (at 90º compared to the previous one) tray # 1 corresponds with the one located in the lower position and No. 16 with the one located in the top position.

The splice tray allows you to store a maximum of 32 double layer joints, (with protectors 2.6 mm diameter heat shrink) and the additional length of fiber corresponding to each of them. In use usual, only 16 joints per tray will be accommodated. Design internal tray allows a minimum radius of curvature of 30 mm in the path of the fibers inside the tray.

From the point where the cables are tied External plant removes the cable cover and loose tubes of the same are guided to the splice trays, whose entrances elements are available to fix said loose tubes by headbands

The connection between splice trays and modules of connection is made with monofibre rails of 1.2 mm in diameter and SC / ACP connector at one of its ends. From each splice tray a mallet of 16 rabs comes out from the left side of it, which they will be fixed to the entrance of the tray with belts.

The rabillos are guided towards the bottom of the distributor where there is a roller (13) bending for the curvature control (fig. 2 and fig. 3), from which lead up to the zone of connection modules (3).

In the lower back, on the bottom of the frame (1) are clamps to fix the cables input multifiber. On the left side of the frame and along the entire side, several sets of clamps to fix and guide the multifiber cables that go to access the dealer through the top of it.

In addition, on the splice module (2), as Figure 5 shows, thread guides (16) are arranged, for management of supervisory cords.

For their part, and as noted above, the connection modules (3) are located above the module connection (2), with a total of 16 connection modules pivot in termination configuration up to 288 f.o. (fig. 5 and fig. 6). A connection module (3) incorporates a maximum of eighteen adapters (17) arranged in two rows of nine units (as shown in figure 5), these being preferably of type SC / APC, although the distributor is susceptible to accommodate other types of connectors and / or adapters. The connectors of the cords from the transmission equipment are inserted frontally in the connection modules (3).

The connectors of the monofibre loops (18) that interconnect splice module (2) and connector modules (3) they are inserted into the latter internally, from behind, as is see in figure 6.

Likewise, each of these monofiber rabbils with SC / APC connector is coded with a number from 1 to 256, according with the position it occupies in the dealer.

The delivery cords of the distributor towards the transmission equipment will be guided to the right side of the connection modules and, through rings (19) with curvature limiter (fig. 5), will run down to access the area of storage of the excess cable length (fig.
7).

In each of the 32 rows of adapters (17), the position on the left is reserved for fiber monitoring in service, the rest of the adapters in each row are numbered correlative, starting with 1, from left to right and from above down. In this way positions 1 to 256 are dedicated to the interconnection of 256 network fibers with as many coming from transmission equipment Positions S1 to S32 constitute the adapters sector for supervision and allow to establish the connection of said fibers to the supervision teams located in central.

Thus, as noted, the adapters (17), whether SC / APC or other, associated with monofiber rails (18) that connect the connection modules (3) with the splice module (2) is inserted into the adapters (17) of the connection modules (3) on the inside (fig. 6).

Inside the module the rabillos are route threads (16) and control elements of curvature to the left and to the bottom of the structure of the frame (1). In each connection module (3) a total of 16 rabillos, which are joined with a strip of Velcro® type tape. Every harness leads to the lower part of the dealer for access to the trays (10) of the splice module (2).

The 16 rabillos from a module connection (3), end in the same splice tray (10), of so that the corners corresponding to positions 1 to 16 of connection, will end in splice tray # 1 and so successively.

The right half of the rack (1) of the dealer It is reserved as an area for the guidance, management and storage of monofiber cords from transmission equipment and supervision, which we have called a guidance module and cord storage (4) (fig. 7 and fig. 10).

This module consists of removable support on which are arranged a series of support plates (22) and hangers (21) that allow the guidance and storage of the length leftover monofiber cords leaving the frame (1) towards Transmission equipment A handle (23) located in the middle of the mentioned support, facilitates the extraction of the same.

The hanger system (21) allows storing the leftover length of the laces in an orderly manner individualized (fig. 7 and fig. 10).

The cords coming from the equipment of transmission and supervision access the distribution cabinet on the part upper right of the frame (1) where an opening is provided (7) for this purpose (fig. 9), and they are guided down to the area of hangers through a curvature limiting element (20) located at the bottom of the frame (1) (fig. 7 and fig. 10).

Along the entire side, a total of twelve hangers (21) in parallel arrangement to the bottom of the frame (1), for storing excess cable of the cords and a series of support plates (22) for guiding the cords.

In addition, between the described guidance module and the right side wall of the frame, a series of tabs are located, to guide the monofiber cords, on their way to the exit of the frame, which is always done by the upper right of the same.

Thus, each cord is then positioned on the corresponding hanger (21) depending on its length, descending on the inside of said hanger to another limiting element of curvature (20) and continuing its path to the left, to finally ascend to the zone of connection modules.

This cord management system allows be able to access any position in the connection module (3) with a standardized cord length of 5.5 meters from the entrance to the deliveryman and store the excess cable on the hangers of the guidance and storage module (4).

The lower cable entry is located located in the lower central area, at the base of the frame (1), shown in figure 8. Through it the cables will access multifiber

On the bottom of the frame are placed a total of 6 clamps, positioned in two rows of 3 elements each.

As can be seen in the aforementioned figure 8, on a provided hollow of the base of the frame (1) through which the cables, it is planned to place a piece of rubber (24) in the that holes (6) have been made for cable entry, which allows the insertion of the cable from the false floor and the Inlet hole sealing.

In the upper left lateral area (fig. 9) of the frame (1) an opening (7) is provided for the entrance of upper cables. On the left side of the dealer is They have 4 groups of 6 clamps (not shown), described above: a group at the top, another at the bottom and two distributed along the side. These groups will serve to the guidance and fixation of the multifiber cables that access the dealer for the top of it through the aforementioned opening (7).

In the upper right is the third cable access, consisting of a second opening (7 '), which will be used for the exit of the cords.

Both upper (7, 7 ') cable entries, they have a brush to minimize the entry of dust to the delivery man.
