Title: Coated optical branching fiber with multi-fiber optical connector
Inventor: TAKIZAWA KAZUHIRO
IPC: G02B6/40
Filed: 2000-05-08
Abstract: PROBLEM TO BE SOLVED: To branch optical fibers into separate coated optical fibers inside a multi-fiber optical connector. SOLUTION: Optical fibers 11 with the ends fixed on a ferrule 2 are each branched directly from the rear opening of a connector as a single-core optical fiber. For example, a tube 12 is put loosely on each optical fiber 11 fixed on a ferrule 2, with each tube 12 being retained at the rear opening of the connector. The tube 12 with the optical fiber 11 stored constitutes a coated optical fiber. It is desirable that tubes 12 at the rear end of the connector be arrayed in a chevron shape. At connector fitting operation (connecting operation), even if the ferrule 2 retreats by coming into contact with the ferrule of the opposite multi fiber optical connector, since the optical fiber 11 is stored simply loosely in the tube 12 without being restrained by the connector, it retreats together with the ferrule 2.  The optical fiber 11 is free of a compression force, thus eliminating the possibility of causing bending to deteriorate transmission characteristics. The array in chevron, at the rear end of the connector of the tube 12 containing the optical fiber 11, makes the connector width compact.
