SMALL DIAMETER, HIGH STRENGTH OPTICAL FIBER

摘要

A coated optical fiber, preferably a GGP optical fiber includes an optical fiber core, and a silica cladding over the optical fiber core, to provide a silica clad core. A permanent polymeric coating forms on the silica cladding during ultraviolet radiation of a photocurable composition containing a non- hydrolyzable photoinitiator. The coated optical fiber has a diameter from 12 0 microns to 160 microns and a relative frequency distribution of at least 85 % for dynamic fatigue measurements between 49.2 x 103 kg/cm2 (700kpsi) and 63. 3 x 103 kg/cm2 (900kpsi).
