1. A curing apparatus for curing a coating composition disposed on an optical fiber, the curing apparatus comprising:
a first light source and a second light source such that the second light source is spaced from the first light source with a gap;
a first reflector and a second reflector such that the second reflector is spaced from the first reflector with the gap; and
a spacer disposed within the gap, the spacer formed of a material configured to reflect at least about 90% of light emitted from the first light source and from the second light source, and incident on the spacer, to an optical fiber such that the reflected light has sufficient intensity to cure a coating on the optical fiber.
