METHOD FOR MANUFACTURING METAL COATED OPTICAL FIBER

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a metal coated optical fiber in which electric power can be easily and stably supplied for forming a metal coating layer on a seed layer by electroplating and high productivity, high quality and high economic advantage can be achieved. SOLUTION: When a metal coating layer is formed by electroplating on the surface of a conductive seed layer 4 which is applied on a primary coated fiber 3 and is exposed by removing a resin coating 2 in a required length of an optical fiber 1, the top end of the primary coated fiber having the exposed sheet layer 4 is gripped and supported by a pair of gripping pieces 5a, 5b at least one of which is made of a conductor. The conductor gripping piece 5a is used as a cathode to supply electric power. The conductive gripping piece 5a is masked with an insulator except at the part being in contact with the primary coated fiber 3 having the seed layer 4. COPYRIGHT: (C)2005,JPO&NCIPI
