    Abstract: A radiation curable coating composition for an optical fiber comprising: at least one urethane (meth) acrylate oligomer, at least one reactive diluent monomer and at least one photo initiator is described and claimed. The composition is capable of undergoing photopolymerization when coated on an optical fiber and when irradiated by a light emitting diode (LED) light, having a wavelength from about 100 nm to about 900nm, to provide a cured coating on the optical fiber, with the cured coating having a top surface, and the cured coating having a Percent Reacted Acrylate Uπsaturation (%RAU) at the top surface of about 60% or greater. Also described and claimed are the process to coat an optical fiber with the LED curable coating for optical fiber and a coated optical fiber where the coating has been cured by application of LED light.
