Frame with insert for a coupling field between fiber optic cables

The innovation relates to a frame with an insert for a coupling field between fiber optic cables and devices for further processing the signals that are transmitted via the individual fibers, in which a slide-shaped holding device for the fiber optic connectors forming the coupling field is provided on a mounting wall arranged vertically approximately in the middle of the frame and can be pulled out in a horizontal direction towards the front of the insert. The holding device holds the individual connectors in a clampable manner at an angle of approximately 45° to the vertical and can then be moved into the insert.

Such a device is known from DE-OS 35 11 653, in which fiber optic connectors that can be pulled out of the frame are combined in a coupling field in a single frame. The multi-core fiber optic cable is led from the cable grid downwards in the frame to a so-called splice module, from where the fiber optic individual wires lead upwards via the connectors to the connected devices, for example line terminals. However, it is required for such devices that they can be easily shunted.

The aim of the innovation is to provide a simple solution to this problem.

This task is solved according to the innovation, starting from a device of the type mentioned above, in that the trunk cable in multi-fiber design is routed on the left in a double frame from the grid above to a grid at the bottom.

in the frame are led to the splice module, from which the fiber optic cables are first led upwards, then in loops back down and then also in the left corner of the frame and finally divided into permissible loops of a reversing loop each to the fiber optic connectors located very low in the middle of the frame, from the lower part of which they are led again in a reversing loop on the right in the frame up to the cable grid and the subsequent signal processing devices.

The innovation and its advantages are explained in more detail below using an example shown in the figure.

The figure shows a double frame with d*n for the construction

7R characteristic mounting profiles 1 and the two narrow frames 2 and 3. Within the left narrow frame 2, the multi-fiber trunk line 4 leads from above, i.e. coming from the cable grid 10, in the left rear corner of the frame from above to the splice module 5 arranged at the bottom. Single-fiber distribution lines 8 lead upwards from this splice module, which are initially gathered together in a loop downwards to form a bundle, which in turn is guided upwards in the left rear corner of the narrow frame 2. There, the single-fiber cables are gathered together via cable ducts 14 or cable ties 14 and individual smaller bundles are branched off upwards. These individual cable cores are guided via a reversing loop 11 to fiber optic plug connections held diagonally from top left to bottom right in the middle of the frames. After these plug connections, the individual cable wires are first led downwards on the fenestrated side of the fenestrated narrow frame and then upwards again in another reversing loop 12, where they are gathered together in a bundle 7 held by cable holders 15 on the side wall and led over the cable grid 10 to the signal processing devices. The multiple looping of the individual fiber cables described above creates an easy possibility.

The bending radius for individual fibers is easy to maintain if the lengths of the individual cables are measured accordingly. In this case, the smallest possible bending radius for individual fibers is easy to maintain. In contrast to the known holders for the fiber optic connectors described at the beginning, in this case these connectors are rotated by 90°. Otherwise, the type of holder for these fiber optic connectors described in the state of the art is retained, but is arranged between the two narrow frames. To cover the frame,
