Abstract: An infinite network polymer containing fluorine as a coating or cladding material for optical fibers. Fluoropolymers, such as silicone amine C.sub.0 -C.sub.16 fluoroepoxy resin and cis-trans fluoropolyol polyacrylate, reduce water permeability because of the bonding between the fluoropolymer and the substrate.

Incorporation of fluorine into the polymer structure lowers the index of refraction such that the polymer can be used as a cladding for silica glass in an optical fiber. One fluoropolymer formulation allows in-line coating of the optical fiber in a oxygen environment.
