Abstract: An optical fiber draw system that prints one or more fiber identifiers on optical fibers is described. In one example, the optical fiber draw system includes a draw furnace, a coating device, a marking device, and a lighting device. The draw furnace generates a glass fiber from a glass preform and the coating device is configured to apply a curable coating composition to the glass fiber. The lighting device applies an ultraviolet or other curing light to form a coating from the curable coating composition. The application and curing of a curable coating composition can be completed one or more times to form one or more coatings on the glass fiber. The marking device applies a tracer marking fluid to a curable coating composition or coating and can be placed at one or more positions along the process pathway.

Abstract: A method of marking an optical fiber that includes directing a laser beam onto a first colored layer of an optical fiber. The optical fiber includes a core and a cladding surrounding the core, the first colored layer surrounds the cladding, and the laser beam modifies the first colored layer to form one or more laser-modified regions along an outer surface of the first colored layer.
