Abstract

Described herein are methods of producing a coated optical fiber from a primary and/or secondary coating composition that contain a reactive oligomer having an average of at least one polymerizable group, a monomer having an average of at least one polymerizable group, and a photoinitiator, wherein the photoinitiator possesses specified normalized rates of polymerization at (150) degrees Celsius and/or a potential excited triplet state with certain ionization potential values. Also described and claimed are the compositions for use therewith, including primary coating compositions and secondary coating compositions. Yet further described and claimed are the coated optical fibers produced from the methods and/or compositions elsewhere described.
