ABSTRACT:
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 cable2of a trunk line, a branch portion11is disposed. The branch portion11has: a base member16which is attached so as to cover a tensile-strength wire9in a portion where a cable jacket10of the multi-core optical fiber cable2is removed away; a multi-core optical connector30which is connected to the tip end of a tape unit4drawn out from the multi-core optical fiber cable2; an extra-length housing portion18which houses an extra length of the tape unit4to which the multi-core optical connector30is connected; and a connector attaching portion19to which the multi-core optical connector30is attachable in a plural number.
