Abstract: An optical fiber production system is provided which includes a slow-cooling device and a purge device positioned above the slow-cooling device. The purge device includes a tube defining an inlet. An optical fiber extends through the slow-cooling device and the purge device. The purge device is configured to inject a purge gas through the inlet and against the optical fiber.

Abstract: An optical fiber with low fictive temperature along with a system and method for making the optical fiber are provided. The system includes a reheating stage that heats the fiber along the process pathway to a temperature sufficient to lower the fictive temperature of the fiber by relaxing the glass structure and/or driving the glass toward a more nearly equilibrium state. The fiber is drawn from a preform, conveyed along a process pathway, cooled and subsequently reheated to increase the time of exposure of the fiber to temperatures conducive to lowering the fictive temperature of the fiber. The process pathway may include multiple reheating stages as well as one or more fiber-turning devices.

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.
