要がある。(Prior art) Although the technology for sending metal cables with metal wire cores to subscribers has been established, it is difficult to apply this metal cable drop-off box technology to optical cable drop-off boxes.
This is impossible because there are problems specific to optical cables (particularly problems with optical fiber connection technology). However, just like with metal cables, optical cables also need to be debited when subscriber demand occurs, and there is an urgent need to establish this technology. In particular, in the case of optical cables, it is necessary to leave extra length in the optical fiber core at the drop-off point in case of connection changes or reconnections, but this extra length can cause connection failures. etc., it is not always possible to secure a constant length, and it is necessary to safely store such an unconstant surplus length. Furthermore, when storing the extra lengths of a plurality of optical fibers, it is necessary to make maintenance easy.
