Optical Fiber Branch Cable, Method of Wiring the Same, and Method of Providing the Same

摘要

An optical fiber branch cable is provided that comprises a branch portion disposed stably with respect to a multi-core optical fiber cable of a trunk line from which branching is performed, that is excellent in handleability as a cable, and that exhibits high workability. In the optical fiber branch cable of the invention, in a middle of a multi-core optical fiber cable 2 of a trunk line, a branch portion 11 is disposed. The branch portion 11 has: a base member 16 which is attached so as to cover a tensile-strength wire 9 in a portion where a cable jacket 10 of the multi-core optical fiber cable 2 is removed away; a multi-core optical connector 30 which is connected to the tip end of a tape unit 4 drawn out from the multi-core optical fiber cable 2; an extra-length housing portion 18 which houses an extra length of the tape unit 4 to which the multi-core optical connector 30 is connected; and a connector attaching portion 19 to which the multi-core optical connector 30 is attachable in a plural number.
