Title: Flexible multicore optical fiber
Inventor: YOKOYAMA KENJI
IPC: G02B6/00
Filed: 1997-12-19
Abstract: PROBLEM TO BE SOLVED: To provide a flexible and easily wirable multicore optical fiber composed of any coated optical fibers by fixing only and end part. SOLUTION: In this multicore optical fiber composed of any coated optical fibers, only the end part 3 is fixed. That is, many optical fibers 2 are not fixed to each other except for the end parts 3 and only the end parts 3 are fixed in a tape shape. Thus, it can be bent in all directions. However, the optical fiber 2 unfixed at the middle part lack mechanical strength. Thus, a tube made of rubber or plastic or the like is provided so as to protect the optical fibers 2 not fixed to each other. Thus, the mechanical strength and flexibility are held. Since the multicore optical fiber prepared in such a manner is full of flexibility, wiring is facilitated.
