OPTICAL PARTS HOUSING FRAME DEVICE

摘要

PROBLEM TO BE SOLVED: To facilitate the wiring and wiring change of optical fibers for connection and to improve the reliability of optical connection of optical parts to each other by arranging plural rows of second optical parts on the lower sides of trays for wiring along a longitudinal direction on the lower side of the trays for wiring. SOLUTION: The upper side of optical fiber junctures 41 for optical branching modules 4 is provided with the trays 28c for wiring which are mounted with the optical fibers 6 for connection and introduce the optical fibers to the optical branching module 4 side. Plural optical fiber supporting parts 48 for dividing and supporting the optical fibers 6 for connection introduced into the trays 28c for wiring in correspondence to the number of the optical fiber junctures 41 of the respective optical branching modules 4 are installed in combination in the longitudinal direction of the trays 28c for wiring. The respective optical fiber supporting parts 48 are disposed to offset successively in the positions of the direction orthogonal with the longitudinal direction of the trays 28c for wiring. As a result, the hanging down of the optical fibers 6 for connection like a bamboo blind on the trays 28c for wiring is prevented and the wiring and wiring change of the optical fibers 6 for connection are made extremely easy.
