BARE OPTICAL FIBER, OPTICAL FIBER TAPE CORE, AND OPTICAL FIBER CABLE

摘要

Disclosed are a bare optical fiber, optical fiber tape core, and optical fiber cable whereby both increases in transmission losses and decreases in intensity are reduced. Said bare optical fiber comprises an optical fiber with a primary cladding layer covering the outer surface thereof and is characterized in that said primary cladding layer contains a UV-curable resin which contains, by mass, 0.05-0.75 parts of a reactive silane coupling agent and 0.05-0.75 parts of a non-reactive silane coupling agent.
