Branch device for multi-core optical fiber.

摘要

In a branch device for a multi-core optical fiber (1), a branch portion protector (10) which includes a spindle-shaped protector (11) and a perforated member (12) which are integrally formed with each other is provided between the end portion of the multi-core optical fiber (1) and the single-core optical fiber protection tubes (15) so that no excessive force is exerted on the branching-out single-core optical fibers (2) and the optical loss is stable.
