The back can be used to avoid congestion.

[0016]

The optical cable connection module according to the present invention has the following features. 1) In a cabinet that can be accessed only from the front, congestion can be avoided by separating the external cable and the internal cable vertically. 2) so as not to interfere with the lateral wire upon insertion of the module, the back of the wire tray is in the module top dead de space <br/> scan occurs, by utilizing a table / back of the wiring trays,
There is no need to provide two levels of wiring trays for the intra-office cable and the out-of-office cable, and the dead space can be reduced.

3) The insertion / removal of the tray always causes a change in the wiring route of the external cable, so it is necessary to absorb this extra length difference. However, if this is done on the front of the module,
It is necessary to provide an extra length absorption space at the upper part so as not to hinder the insertion and removal of the adjacent module. According to the present invention, by performing this at the top of the module dead de space, since the front is clean, it is not necessary to increase the extra dead de space. 4) The partition plate can prevent the extra length of the external cable from becoming entangled with the adjacent modules and hindering the insertion / extraction of the tray for storing the connection portion of the external cable. 5) For example, when the number of cores of the module is eight and the number of cores of the external cable is four, the remaining four cores are not affected without affecting the four cores on the previously connected communication line. Can be connected.
