Abstract
Compositions for use in optical fiber coatings and optical fibers and optical fiber arrays using these coatings are disclosed, as are methods for making the same. The compositions comprise a combination of two different radiation curable urethane oligomers, and can further comprise one or more reactive monomers. One of the oligomers has at least three functional groups that can undergo radiation cure, and comprises a lactone modified polyol.
