Abstract
The deleterious generation of hydrogen in optical fiber cables with cured silicone resin coatings is reduced by treating such optical fibers with one or more type of olefinic hydrocarbon to convert --Si--H groups remaining after curing to --Si--R groups where R is an alkyl group having the same number of carbons as the one or more type of olefinic hydrocarbon. The resulting optical fiber cable, having a light transmissive core surrounded by one or more glass cladding layers, is coated by a cured, silicone polymer having few, if any, residual --Si--H groups.
