Abstract
The invention provides an optical glass fibre having a synthetic resin cladding and a method of manufacturing same, in which the first layer of the synthetic resin cladding is formed from a curable polysiloxane composition. The curing rate is increased by the presence of acrylate groups. The refractive index (exceeding 1.46) and the glass transition temperature (lower than -50.degree. C.) can be adjusted by the ratio of the dimethyl siloxane groups, methyl phenyl siloxane groups and diphenyl siloxane groups present. The curing rate can furthermore be increased by the addition of monomeric acrylate compounds.
