The invention provides an optical fibre having a synthetic resin cladding, comprising a glass fibre, a first cladding layer of a synthetic rubber and a subsequent cladding layer of a synthetic resin the molecules of which are oriented substantially in the longitudinal direction of the glass fibre, in which a low application temperature, a low pressure and a high cladding rate can be used in that the oriented synthetic resin is formed from a curable synthetic resin composition which comprises one or more oligomeric compounds the molecules of which comprise reactive groups and the molecular weight of which is smaller than 5000. The invention further relates to a method of manufacturing such an optical fibre and a device for cladding a glass fibre with a curable synthetic resin composition in which an elongation flow in the curable synthetic resin composition is produced to effect the orientation in the curable synthetic resin composition.
An optical fibre having a synthetic resin cladding, comprising a glass fibre, a first cladding layer of a synthetic rubber and a subsequent cladding layer of a synthetic resin the molecules of which are oriented mainly in the longitudinal direction of the glass fibre, characterized in that the oriented synthetic resin is formed from a curable synthetic resin composition which comprises one or more oligomeric compounds the molecules of which comprise reactive groups and the molecular weight of which is smaller than 5000.
A method of manufacturing an optical fibre, characterized in that a curable synthetic resin composition which comprises one or more oligomeric compounds the molecules of which comprise reactive groups and the molecular weight of which is smaller than 5000, is applied to a glass fibre having at least one enveloping layer of synthetic rubber, in which the molecules of the curable synthetic resin composition are oriented during application to the glass fibre, after which the curable synthetic resin composition is made to cure while forming a synthetic resin the molecules of which are oriented substantially in the longitudinal direction of the optical fibre.
