PROBLEM TO BE SOLVED: To reduce breakages, etc., of an optical fiber cable, a plug, an optical connector, etc. SOLUTION: A recessed part 12 is formed in part of the flank of a housing 1 and part of the bottom surface and is put back inside other external surfaces. Optical connectors 5a, 5b, 5c, and 5d are fitted to the reverse surface of the recessed part 12, and internal pigtail fibers 3a to 3d and external optical fiber cables 6a, 6b, 6c, and 6 and connected via optical connector plugs 7a, 7b, 7c, and 7d. The optical connectors 5a, 5b, 5c, and 5d are fitted vertically, since no bends are formed on the optical fiber cables 6a to 6d has and they are inside the surface of the housing 1, the optical fiber cables, plugs, optical connectors, etc., have less breakages and so on. |
