Abstract
A method for manufacturing a coated optical fiber including the step of determining a desired temperature operating range of a coated optical fiber having at least one critical limit. The intercoating delamination stresses at the critical limit of said temperature range are determined. A zero-stress temperature region using the critical limit and the delamination stresses is then selected. An optical fiber is provided and the optical fiber is coated with a first polymer coating. The first polymer coating is exposed to a source of actinic radiation, wherein the source of actinic radiation generates heat. A second polymer coating including a photopolymerizable composition is applied to the optical fiber directly on the first polymer coating. The second polymer coating is cured, where at the time the second polymer coating is cured the first polymer coating is at the zero-stress temperature region.
