<p><P>PROBLEM TO BE SOLVED: To provide an optical branch cable and its wiring method with which wiring cost can be reduced by reducing an mount of wiring work of optical fiber cables which are to be wired in a building, such as an office building, an apartment house. <P>SOLUTION: One terminal of a trunk cable 3 composed of coated optical fibers of 32 cores is connected to a distributing frame 1 and other terminals of the trunk cable are connected to branching parts 5. One terminal of each indoor cable 4 is connected to information distribution boards 2 and other terminal is connected to the branching part 5. In the branching part 5, coated optical fibers of the terminal of the trunk cable 3 are branched into optical fibers and these branched optical fibers are connected to the optical fibers of the indoor cables 4. Moreover, lengths of the trunk cable 3 and the indoor cables 4 are preliminarily adjusted and prepared to required lengths respectively. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
