Abstract
A novel all-plastic optical fiber comprising core and clad components which is tough, flexible, and which has a low transmission loss, wherein the core component is composed of a homopolymer or copolymer of a monomer selected from one or more monomers represented by the general formula (I), or a copolymer of the at least one monomer represented by the general formula (I) and other copolymerizable comonomers and which has a glass transition temperature Tg.sub.1 .degree. C.; and wherein the clad component is composed of a copolymer of perfluoro[2,2-dimethyl-1,3-dioxol] and one other ethylenically unsaturated monomer, and which has a glass transition temperature Tg.sub.2 .degree. C.; and which meets the relationship wherein that the absolute difference of .vertline.Tg.sub.1 -Tg.sub.2 .vertline. is not greater than 30.degree. C. ##STR1## (wherein X is CH.sub.3, H, D, F, Cl, or CF.sub.3 ; Y is H or D; and Rf is a fluoroalkyl group having a linear or branched chain).
