Abstract

A reinforced glass fiber for use in optical transmission comprising an optical fiber coated with (1) a coating of a first curable organopolysiloxane composition having a refractive index higher than that of the clad glass which forms the outermost layer of the optical fiber, said first curable organopolysiloxane composition being baked, (2) a coating of a second curable organopolysiloxane composition which can be the same as or different from the first curable organopolysiloxane composition, the second curable organopolysiloxane composition being provided on the first curable organopolysiloxane composition and being baked, and (3) optionally a coating of a thermoplastic resin composition.
