SYSTEMS AND METHODS FOR PROCESSING OPTICAL FIBER

Abstract:

A system for processing an optical fiber includes: a draw furnace, said draw furnace containing an optical fiber preform; a bare optical fiber drawn from said optical fiber preform, said bare optical fiber extending from said draw furnace along a process pathway; and a slow cooling device operatively coupled to and downstream from said draw furnace, said slow cooling device exposing said bare optical fiber to a slow cooling device process temperature in the range from 1000.degree. C. to 1400.degree. C., wherein the bare optical fiber passes through the slow cooling device at least two times.
