Method of manufacturing an optical fiber having coatings of distinct kinds

摘要

A method of coating an optical fiber constituted by a doped silica core ( 1 ) and by silica cladding ( 2 ) consists in surrounding the doped silica core ( 1 ) and the silica cladding ( 2 ) in coating constituted by a first coating portion ( 3 ) of photocurable resin and a second coating portion ( 4 ) made by extruding a thermoplastic polymer.
