Abstract
A plastic optical fiber which is a graded index optical fiber having a concentric inner/outer at least two layer structure, wherein the inner layer has a graded index structure made of a non-crystalline fluoropolymer (a) having substantially no C—H bond, and the outer layer has a refractive index lower than the refractive index of the outermost portion of the inner layer and is made of a fluoropolymer material (c) selected from the following 1) and 2): 1) a fluoropolymer (d) containing the same polymerized units as the polymerized units in the fluoropolymer (a), and 2) a mixture (f) of a fluoropolymer (a) with another fluoropolymer (e).
