METHOD AND APPARATUS FOR COATING OPTICAL WAVEGUIDE FIBERS

摘要

A method and apparatus is provided for controlling the diameter of a coated optical waveguide fiber. The viscosity profile of the coating material is controlled by adjusting the temperature of a portion of the coating assembly based on a measurement of the diameter of the coated fiber. By controlling the viscosity profile of the coating material, the amount of coating applied to the fiber is controlled, thereby determining the diameter of the coated fiber.
