摘要： A method of manufacturing optical fiber in an optical fiber production system is provided. The method includes the providing a draw furnace operatively coupled to a slow cooling device along a draw pathway, drawing the optical fiber from an optical fiber preform in the draw furnace and along the draw pathway, heat treating the optical fiber in the slow cooling device positioned along the draw pathway, the slow cooling device comprising an inlet, an outlet, and a process tube extending between the inlet and the outlet, and selecting an opening size of an outlet nozzle operatively coupled to the outlet based on a draw speed of the optical fiber.
