1. A reinforced glass fiber for use in optical transmission comprising an optical fiber having provided thereon (1) a coating of a first curable organopolysiloxane composition having a refractive index higher than the glass which forms the outermost layer of the glass fiber, said first curable organopolysiloxane composition being baked to cure the same, and (2) a coating of a second organopolysiloxane composition which can be the same as or different from the first curable organopolysiloxane composition, said second curable organopolysiloxane composition then being provided on the first curable organopolysiloxane and being baked to cure the same, wherein at least one of the first and second curable organopolysiloxane compositions has a stress absorbing effect and a Young'"'"'s modulus lower than 2.0 kg/mm2 at room temperature.
