ABSTRACT:
An optical fiber with low attenuation of light transmission comprising a core and a cladding, wherein the core is made of a polymer comprising units of deuterated methyl methacrylate containing 10 to 40% of a methacrylic ester the ester moiety of which has an alicyclic hydrocarbon group of from 6 to 20 carbon atoms, and the cladding is made of a transparent polymeric material having a refractive index of at least 3% smaller than that of the core, which optical fiber has excellent heat and humidity resistance as well as good flexibility.
