ABSTRACT:
A plastic optical fiber comprising a core and a cladding, wherein the core is made a polymer comprising units of methyl methacrylate and of a methacrylate ester, the ester moiety of which has an alicyclic hydrocarbon of 8 to 20 carbon atoms, and the cladding is made of a fluorine-containing polymer comprising units of the formula: ##STR1## wherein R.sub.1 and R.sub.2 are each hydrogen or C.sub.1 -C.sub.3 alkyl, R.sub.f1 is fluorine or trifluoromethyl, an R.sub.f2 is C.sub.2 -C.sub.10 fluoroalkyl, which units (I) are derived from fluoroalkyl .alpha.-fluoroacrylate or trifluoromethacrylate, which has short- and long-time heat and humidity resistance as well as low attenuation of light transmission.
