Abstract
An optical fiber draw system and method of coating an optical fiber. The system includes a furnace for heating an optical fiber preform, a draw assembly for drawing the optical fiber at a draw speed greater than 50 meters per second, a first coating applicator for applying a first coating onto the fiber, and a first curing assembly comprising a first plurality of light sources comprising light-emitting diodes for partially curing the first coating. The optical fiber draw system also includes a second coating applicator for applying a second coating onto the fiber on top of the first coating, and a second curing system comprising a second plurality of light sources for curing the second coating, wherein the first coating is further cured in the range of 15-50 percent after leaving the first curing assembly.
