Title: Optical fiber-branched coated optical fiber with multi- fiber optical connector
Inventor: TAKIZAWA KAZUHIRO
IPC: G02B6/40
Filed: 2001-03-06
Abstract: PROBLEM TO BE SOLVED: To prevent an action of excessive bending force from being applied to the connector master part of an optical fiber-branched coated optical fiber. SOLUTION: An optical fiber-branched coated optical fiber 1 with a multi-fiber optical connector is directly branched from the opening part of a connector hinder part by making a plurality of optical fibers 11 whose ends are fixed to the ferrule 2 of a fitting pin positioning system into a single core coated optical fiber. The single core coated optical fiber to be directly branched has a tube structure including the optical fibers in which the optical fibers 11 are covered with tubes 12. The group of the tube 12 including the optical fiber (optical fiber-branched coated optical fiber) is adhered and fixed at the connector side (the adhered and fixed part is indicated by 14), at the inner position with a fixed distance from the opening end of a protective boot 9.  The region (size b of Figure 1) from the opening end of the protective boot 9 to the adhered and fixed part is present as a region where a little bending of the tube 12 including the optical fiber is tolerated. Accordingly, when bending force acts on the tube 12 including the optical fiber outside the connector, the action of excessive bending force to the connector master part can be prevented, and the occurrence of the bending of the optical fibers 11 which deteriorates transmission characteristics can be prevented.
