OPTICAL WIRING RACK AND OPTICAL BRANCHING MODULE

摘要

PROBLEM TO BE SOLVED: To efficiently carry out a work of switching-over or the like of connection of an optical connector for switching-over without affecting an optical communication even in a live-line state.;SOLUTION: The optical branching module 60 for branching and connecting a multi-core optical fiber to a coated optical fiber with an optical connector junction is characterized by the fact that the optical branching module 60 is provided with a main body 72 which houses an optical coupler 77 which is inserted in an optical fiber 76 of which the one end is connected to the multi-core optical fiber and the other end is connected to the coated optical fiber, an optical connector for connection 65 is mounted on an end part of the main body 72, and the optical fiber 76, which is connected by being switched to the multi-core optical fiber on the side of a subscriber via an optical connector for switching-over 85 at a remote position from the main body 72, and an optical fiber 78, of which the end is so formed to be connected to a lead-out cord wired from an optical switch by means of an optical connector for switching-over 86, are led out of the main body 72 from the other end of the main body 72, through cord lead-out ports 81 and 82 which are opened on the other end side face of the main body 72.;COPYRIGHT: (C)2004,JPO
