RADIATION CURABLE RESIN COMPOSITION

摘要

A polymer cladding layer which exhibits a low refractive index, transparency, excellent applicability, excellent adhesion to the core, and excellent strength and flexibility using a known resin material used for a cladding layer of a polymer-clad optical fiber is described and claimed. This polymer cladding layer exhibits stable transparency even when the polymer-clad optical fiber to is exposed to a high temperature.
