METHOD FOR DEHYDRATION USED IN OPTICAL FIBER PREFORM MANUFACTURING PROCESS, AND METHOD AND APPARATUS FOR MANUFACTURING OPTICAL FIBER PREFORM USING THE SAME
Abstract:
Disclosed are a method for dehydration used in the optical fiber preform manufacturing process, and method and apparatus for manufacturing an optical fiber using the dehydration method. In the dehydration method, when the dehydrating gas is supplied into a tube during the optical fiber preform manufacturing process, dehydration reaction gas included in the dehydration gas is activated using a light source which emits light having a predetermined frequency capable of activating the dehydration reaction gas included in the dehydrating gas into atoms or ions. Then, the method uses the activated dehydration reaction gas generated as a result of the above process to eliminate moisture or hydroxyl group causing optical losses during the optical fiber preform manufacturing process.
