ABSTRACT:
A drawn optical fiber (21) is provided with inner and outer layers (42,44) of coating material to protect the optical fiber during handling and use. The coating materials are such that they are characterized by being curable upon exposure to different portions of the light spectrum. In a preferred embodiment, the coating material of the inner layer includes a photoinitiator which absorbs light in the visible portion of the light spectrum whereas the outer coating material of the outer layer includes a photoinitiator which absorbs light in the ultraviolet light portion of the light spectrum.
