  • CLEANING STEP TO REMOVE METALS OR METAL OXIDES FROM POROUS GLASS BODY
    Publication number: 20240360024
    Abstract: A method of manufacturing including: (a) a first vapor deposition step comprising vapor depositing a first porous glass body of a glass former and a doping constituent onto a substrate; (b) a cleaning step after the first vapor deposition step, the cleaning step comprising exposing the first porous glass body to a cleaning gas at a cleaning temperature for a cleaning period of time, the cleaning gas (i) removing a metal or metal oxide from the first porous glass body, (ii) changing an oxidation state of a metal or metal oxide within the first porous glass body, or (iii) a combination of (i) and (ii); and (c) a second vapor deposition step after the cleaning step, the second vapor deposition step comprising vapor depositing a second porous glass body of the glass former onto the first porous glass body resulting in a porous preform for an optical fiber.

  • SYSTEM AND METHODS FOR PROCESSING AN OPTICAL FIBER PREFORM
    Publication number: 20230312390
    Abstract: A system and methods are described herein for preheating a preform in a preheater furnace and then transferring the preheated preform to a consolidation furnace for chemical treatment and sintering the preform into a clear glass which can be drawn into optical fiber. In addition, the preheater furnace is described herein which is configured to heat the preform per a predetermined heat-profile until the preform is uniformly heated to a temperature above 1000° C.
