摘要：Disclosed is a method for manufacturing an optical fiber preform in MCVD,which simultaneously performs an etching process for injecting a reaction gas for etching
into a tube and a collapsing process for heating and collapsing the tube in order tominimize or eliminate an index dip existing at the center of the preform core. By using thismethod, the index dip phenomenon of the optical fiber preform can be minimized oreliminated, so it is possible to make an optical fiber having improved optical
characteristics, particularly having improvement in a bandwidth and a polarization modedispersion (PMD).
