Abstract

A Method for curing a coating applied to an optical fiber. A water-jacketed UV lamp is provided adjacent a first reflector. An optical fiber is drawn between a second reflector opposite the first reflector and at least one quartz plate, while a cross flow of a cooling gas is passed around the optical fiber. Apertures may be formed in the second reflector for passing the cooling gas while the optical fiber is passed between the second reflector and the at least one quartz plate. Alternatively, two or more quartz plates may be provided and the cooling gas and the optical fiber passed between the quartz plates. The cooling gas experiences laminar flow.
