Abstract
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.
Claims12
A method of coating an optical fiber constituted by a doped silica core and silica cladding, in which said core and said cladding are surrounded by a coating constituted by a first coating portion of photocurable resin and a second coating portion made by extruding a thermoplastic polymer, said thermoplastic polymer having mixed therein an additive constituted by a thermotrophic liquid crystal polymer.
An optical fiber constituted by a doped silica core and silica cladding in which said core and said cladding are surrounded by a coating constituted by a first coating portion of photocurable resin and a second coating portion of thermoplastic polymer containing an additive constituted by a thermotropic liquid crystal polymer.
