Description of the Related Art Usually, an optical fiber cable is drawn into and fixed to an entrance of an optical fiber cable housing device (hereinafter, simply referred to as "device"), and then its core wire is connected to the optical fiber cord, and the optical fiber cord is connected to the device. Wired inside. Although this connection is made by fusing work, the length of the optical fiber cord in the device is not constant. Further, generally, there are many core wires of the optical fiber cable, and it is difficult to perform the work by matching the length of the optical fiber cord connected by fusion work to the wiring length required in the apparatus. Therefore, a surplus length of the optical fiber cord is generated in the device, and a surplus length processing unit is provided to process the surplus length.

光ファイバケーブル１１と光コネクタ１６との間の距離

仮定する。Conventionally, the extra length processing section has performed extra length processing using reels and bobbins. 8 to 10 schematically show a general configuration of a surplus length processing unit when a reel is used as the conventional surplus length processing. 8 to 10, 4 is a reel, 11 is an optical fiber cable, 12 is an optical fiber cord, 13 is an optical fiber cable fixing metal fitting, 14 is an optical module, and 16 is an optical connector. The fixed optical fiber cable 11 is connected to the optical fiber cord 12 by fusion work,
The optical connector 16 connected to the end of the optical module 14
The surplus length processing when connecting to is described. In addition,
It is assumed that the distance between the optical fiber cable 11 and the optical connector 16 is 100 mm, and the outer circumference of the reel 4 is 200 mm.

なる。FIG. 8 shows a case where the extra length is completely processed. That is, the length of the optical fiber cord 12 required for the extra length treatment is 300 mm, and the length of the optical fiber cord 12 wound by the reel 4 is 200 in one winding.
mm, since the distance between the optical fiber cable 11 and the optical connector 16 is 100 mm, the total is 300 mm,
The extra length of the optical fiber cord 12 will be completely processed.

うことになる。On the other hand, in the case of FIG. 9, the length of the optical fiber cord 12 required for the extra length treatment is 400 mm, and the length of the optical fiber cord 12 wound on the reel 4 is 1.
Since the number of turns is 200 mm, and the distance between the optical fiber cable 11 and the optical connector 16 is 100 mm, the optical fiber cord 12 is not processed for 100 mm extra length and is left over.

余長をうまく処理することはできないことになる。Further, in the case of FIG. 10, the conditions are the same as those of FIG. 9, but if the number of windings by the reel 4 is two,
The length of the optical fiber cord 12 wound up by the reel 4 becomes 400 mm, the optical fiber cord 12 does not reach the optical module 14, and the optical fiber cord 12 still remains.
The extra length cannot be handled well.

に固定金具等を用いて固定していた。However, the surplus length processing section of the optical fiber cord represented by the surplus length processing using reels and bobbins conventionally occupies a considerable portion in the apparatus. The reason is that the minimum bending radius of the optical fiber cord is specified in advance, and if the bending radius is smaller than that, the optical fiber cord itself will be broken, so the extra length processing part needs to have a certain size. Is. Furthermore, in order to improve workability such as fusion work of optical fiber cords and replacement of optical connectors, a considerable space is allocated in the extra length processing section, and fixing metal fittings are used to prevent the optical fiber cords from breaking. It was fixed.

るようになってきた。従って、余長処理部の小型化と、
作業性の改善が求められてきている。In recent years, as a result of the increase in the number of optical channels accommodated in the device, the miniaturization of the device, and the high-density packaging, a large number of optical fiber cables are accommodated, and as a result, a surplus of optical fiber cords is accommodated. The long processing unit has come to occupy most of the device. Therefore, the extra length processing unit is downsized,
There is a demand for improved workability.

ため、回線数（チャネル数）が増加すると接続替えの光
コネクタの数も増加し、着脱頻度も多くなる。しかしな
がら、接続替えのための十分な空間が確保されていない
ためその作業性は困難を極めている。Further, since the line (channel) is switched by changing the connection of the optical connector of the optical fiber cord, if the number of lines (the number of channels) increases, the number of the optical connectors for changing the connection also increases and the attachment / detachment is possible. The frequency also increases. However, the workability is extremely difficult because a sufficient space for connection change is not secured.

イバコードを折ってしまう等の問題があった。Therefore, it is difficult to associate the optical fiber code with the optical module connected to the optical module, and the optical fiber code of the optical channel of the line to be relocated cannot be accurately identified during the relocation work or the like, and the optical signals of other channels cannot be identified. There have been problems such as removing the fiber cord, accidentally pulling the optical fiber cord of a line that should not be relocated, and in the worst case, breaking the optical fiber cord.

Therefore, even if extra length processing is performed, at the connecting portion of the optical connector of the optical module, an optical fiber cord corresponding to the length of one reel is generated as an extra length at the longest, and wiring becomes complicated and installation work is further required. It was supposed to have poor workability.
