COATING STRUCTURE OF THIN FILM OPTICAL FIBER

摘要

PROBLEM TO BE SOLVED: To provide a coated optical fiber which has a thin film resin layer stopped from peeling off a clad by using a UV curing resin having a low adhesive strength in a second layered coating layer. SOLUTION: In a coating structure of a coated optical fiber 10 where two or three-layered protection coating layers 15 and 16 are provided on a thin film coating layer 14 coating a bare optical fiber 13, the second layered coating layer 15 coated following the thin film coating layer 14 is made of a UV curing resin in which the adhesive strength to the thin film coating layer 14 is≤40g/mm.
