  • the electronic module 17 has a total of twelve plug connectors 22 for connecting a total of twelve plug modules 11 or splice modules.
  • the number of twelve connectors is based on the currently customary arrangement of conventional systems.
  • the number of connectors and thus the number of connector modules and / or splice modules that can be assigned to an electronic module can be between one and the number required for a complete expansion of the distribution cabinet. For reasons of clarity, however, a maximum of sixteen connectors per electronic module should be aimed for. However, several such electronic modules with sixteen connectors can be used until the distribution cabinet or rack has been fully expanded.
  • the electronics module 17 is inserted together with the connector modules 11 into a subrack (not shown), not only do the edges 15 and 18 of the connector modules 11 and the electronics module 17 match, but rather the electronics module 17 also has a front plate 24 with similar dimensions like the front plates 12 of the plug modules 11.

This makes it possible to replace a circuit board 27 without having to interrupt optical fiber connections made via the couplings 14.
  • the connecting cables 21 can be guided in any manner from the plug modules 11 to the electronics module 17.
  • the length and wiring path of the connecting cables 21 can be freely varied, which increases the flexibility of the patch cable management system.
  • the order in which the plug modules 11 and the electronics module 12 are inserted into a subrack is therefore arbitrary. In this way, subracks that are not yet fully equipped can be easily retrofitted with the patch cable management system according to the invention.
  • Power supply lines, address lines and data lines are integrated in each of the connecting cables 21.
  • the plug modules 11 are accordingly supplied with electrical energy via the power supply lines of the connecting cables 21 and thus via the electronic module 17. Via the data lines of the connecting cables 21, the plug modules 11 can be connected to a data bus via the electronic module 17.
  • the address lines of the connecting cables 21 ensure the electronic addressing and location of the inserted optical fiber connections. It is therefore within the meaning of the invention to transfer all functions which are carried out by the so-called backplane in the case of patch cable management systems according to the prior art to a separate module, namely the electronic module 17. This can then be handled like the plug modules 11.
  • FIGS. 3 and 4 show a Patach cable management system 30 according to a second embodiment of the invention.
  • the exemplary embodiment in FIGS. 3 and 4 differs from the exemplary embodiment in FIGS. 1 and 2 only in that the connector modules 11 are connected to the electronic module 17. To avoid repetition, the same reference numbers are therefore used for the same modules.
  • the connector modules 11 are not connected to the electronic module 17 via flexible connecting lines, but via a connector strip 31.
  • the connector strip 31 carries a plurality of connector connectors 32.
  • the connector connectors 32 reach from FIG the back into the plug modules 11 and the electronics module 17. This configuration is particularly advantageous when a clear order of the modules 11, 17 is desired.
  • FIGS. 5 and 6 A further possibility for connecting the plug modules 11 to the electronics module 17 is shown in the exemplary embodiment according to FIGS. 5 and 6. Also in the patch cable management system 33 according to the invention shown there, a plurality of plug modules 11 are connected to the electronics module 17 via a plug connector 34. In contrast to the exemplary embodiment in FIGS. 3 and 4, however, the plug connectors 35 of the plug connector 34 engage in the modules 11, 17 from the front.
  • FIG. 8 shows a plug module 11 with a total of twelve couplings 14 for optical fibers or patch cables.

  • This electronics block 41 contains the already mentioned electronics board 27 as well as the query buttons 28 and the signaling lights 29.

  • the electronic module 17 is used for electronic addressing and the circuit board 27 for the plug modules 11 or splice modules for electronic addressing and location of the plugged-in optical fiber connections.
  • Electronic addressing is to be understood to mean that all the couplings 14 of all plug modules or splice modules can be identified precisely with the aid of a unique address. It must be identifiable which connector 14 is assigned to which connector module 11 and which connector module 11 which electronic module 17. Furthermore, the electronic location is important such that plugged connections of optical fibers (patching), for example between two connector modules 11, can be clearly identified.

  • the electronics module 17 has a switch 38, a so-called DIP switch.
  • the processor 36 of the electronic module 17 and the processors 37 of the respective plug modules 11 communicate via address lines 39.
  • the processor 37, which is assigned to each plug module 11 on the circuit board 27, forms an address for the couplings 14 of the respective plug module 11 assigned to the electronics module 17 is the processor 36, which sends a bit pattern to each of its connected plug modules 11 via the address lines 39, which bit pattern corresponds to an address within the rack.
  • the electronics module 17 has the switch 38, with the aid of which the module rack or the electronics modules 17 in the distribution field, the optical fiber distribution cabinet, is assigned a number.

  • the address lines 39 run within the connector strips 31 and 34, respectively. Since each connector module 11 is connected to the electronics module 17 or to the processor 36 of the electronics module 17 via a separate connector Address line 39 a unique data packet can be assigned, which can be read out by the processors 37 of the connector modules and from which a unique address for each Plug module 11 can be removed.
