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

摘要

PROBLEM TO BE SOLVED: To provide a bare optical fiber, an optical fiber tape core and an optical fiber cable which reduce both increases in transmission losses and decreases in intensity.

SOLUTION: In the bare optical fiber with a primary cladding layer covering the outer surface of the filer, the bare optical fiber is characterized in that the primary cladding layer contains an ultraviolet-curable resin, and the ultraviolet-curable resin contains ≥0.05 and ≤0.75 pt.mass of a reactive silane coupling agent and ≥0.05 and ≤0.75 pt.mass of a non-reactive silane coupling agent.
