摘要:

本文从光纤弯曲损耗的理论入手,重点介绍了光纤弯曲损耗的计算以及弯曲损耗与截止波长、高功率激光注入、光纤寿命等因素的关系,针对弯曲不敏感光纤(G.657)和其他普通单模光纤(G.65x)进行了弯曲损耗的对比测试,以期为光纤接入网的设计和工程技术人员提供参考。

Abstract:

Based on the theory of optica1 fibre bend 1oss,this paper focuses on numerica11y estimating of optica1 fibre bend 1oss.We expound the re1ationships one by one between bending and cut-off wave1ength,bending and high power 1aunch,bending and 1ife of optica1 fibre,and etc..As for bending 1oss insensitive sing1e mode optica1 fibre(G.657)and ordinary sing1e mode optica1 fibre(G.65x),we tested and compared the macrobend 1oss of two kinds of optica1 fibres.The research resu1ts of this paper wi11 offer some usefu1 reference to design and construction engineers of optica1 access network.

Key words: optica1 fibre, macrobend 1oss, macrobend, microbend, bending 1oss insensitive sing1e mode optica1 fibr
