Method of coating and optical fiber comprising polyimide-silicone block copolymer coating

摘要

A silicone-based composite coating system for a glass optical fiber, the system comprising a silicone polymer undercoating component and a silicone-polyimide block copolymer overcoating component, is provided. The coating system can be applied entirely on-line, improves the handling characteristics of the fibers over conventional silicone- coated fibers, offers an excellent combination of optical and elastic properties, and does not compromise the high-temperature operating characteristics of silicone-based coating systems.
