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 to minimize or eliminate an index dip existing at the center of the preform core. By using this method, the index dip phenomenon of the optical fiber preform can be minimized or eliminated, so it is possible to make an optical fiber having improved optical characteristics, particularly having improvement in a bandwidth and a polarization mode dispersion (PMD).
摘要(中):
公开了一种用于制造MCVD中的光纤预制件的方法,该方法同时进行用于将用于蚀刻的反应气体注入到管中的蚀刻工艺和用于加热和塌缩管的塌缩过程,以便最小化或消除存在于 预制核心的中心。 通过使用这种方法,可以使光纤预制棒的折射率现象最小化或消除,从而可以制造具有改善的光学特性的光纤,特别是带宽和偏振模色散(PMD)的改善。
