Patent ID: 8871311

Claim:
A method for curing a coating on a glass fiber, comprising: providing a cavity that defines a curing axis; passing a glass fiber having a substantially uncured coating through the cavity and along the curing axis, the coating having a first absorption peak occurring at a wavelength greater than 300 nanometers, wherein the glass fiber does not possess a substantially uncured coating having an absorption peak that is between 200 nanometers and 300 nanometers; directing UV radiation from a first UV-radiation source to promote the curing of the coating, at least about 80 percent of the electromagnetic radiation emitted by the first UV-radiation source having wavelengths of between about 200 nanometers and 300 nanometers; and directing UV radiation from a second UV-radiation source to promote the curing of the coating, at least about 80 percent of the electromagnetic radiation emitted by the second UV-radiation source having wavelengths within 10 nanometers of the coating's first absorption peak.
