Abstract

PURPOSE:To avoid mixing of impurities or moisture into glass in preparation of material glass for optical fiber to be used for optical communication by forming annular space for gas discharge between the reaction tube wall of a veritical type reactor and the crucible wall to thereby make smaller transmission loss.
