However, in the above-mentioned conventional optical cable housing structure, in order to perform the extra length work by pulling out the extra length treatment shelf, a space for the extra length treatment work is provided in the mounting rack. It is a structure that can not be.
Therefore, as a practical matter, it is necessary to reserve an extra mounting space, which does not save space.

Further, since the electric signal cable is not taken into consideration, it is difficult to connect and house the electric cable on the front surface of the mounting rack.

Further, since the optical cable is subjected to the extra length treatment on the extra length treatment shelf, it is disadvantageous from the viewpoint of protection of the optical cable.

Further, when pulling out the extra length processing shelf during the extra length processing work, it is necessary to remove the optical connector and the adapter in advance, which complicates the work.

It is characterized by comprising a mounting member to be mounted and a locking member for fixing the surplus length processing plate by inclining the surplus length processing plate to the inner side in a state where the optical cable held by the surplus length processing plate faces the inner side. .

Further, the mounting structure for an optical communication device according to the present invention is a mounting structure for an optical communication device in which a plurality of optoelectronic circuit units are mounted in the vertical direction and a heat radiation mechanism for these optoelectronic circuit units is provided. An optical cable extra length processing section and an electrical connector section are provided between the optoelectronic circuit units mounted in the vertical direction, and the optical cable extra length processing section has a wire saddle that detachably holds the optical cable on one surface. A surplus length treating plate, a mounting member for removably and rotatably mounting the surplus length treating plate to the mounting rack, and an optical cable held by the surplus length treating plate facing inward. A locking member that tilts and fixes the extra length processing plate to the inner side in a state where the electrical connector portion is provided on the mounting rack and is held by the extra length processing plate. Is arranged at a position facing the cable, characterized in that.

[0016]

In the optical cable accommodating structure according to the present invention, the optical cable is held by winding the optical cable around the wire saddle of the surplus length treating plate, and the surplus length treating plate is attached to the mounting rack with the optical cable side facing inward. Rotate the processing plate to the inside of the mounting rack and fix it in an inclined state. Therefore, the optical cable subjected to the extra length treatment is accommodated inside the extra length treatment plate.
