Abstract: In some embodiments, a method for processing an optical fiber includes: drawing an optical fiber through a draw furnace, conveying the optical fiber through a flame reheating device downstream from the draw furnace, wherein the flame reheating device comprises one or more burners each comprising: a body having a top surface and an opposing bottom surface, an opening within the body extending from the top surface through the body to the bottom surface, wherein the optical fiber passes through the opening, and one or more gas outlets within the body; and igniting a flammable gas provided by the one or more gas outlets to form a flame encircling the optical fiber passing through the opening, wherein the flame heats the optical fiber by at least 100 degrees Celsius at a heating rate exceeding 10,000 degrees Celsius/second.

Abstract: A method and corresponding apparatus for processing optical fiber include directing light from a directed light source toward an optical fiber on a fiber draw. A fiber core of the optical fiber is heated, using at least the light from the directed light source, to a fiber core temperature within a glass transformation temperature range of the fiber core. The method can be used to reduce fictive temperature of the fiber core, with Rayleigh scattering being reduced, leading to lower attenuation losses in the fiber core.
