使用双向后向散射技术模拟单模光纤模场直径测试

基于双向后向散射技术,光时域反射仪能拟合出单模光纤模场直径的数值。本文通过改变测试条件,以探究不同参考纤、不同接续损耗对后向散射法模拟单模光纤模场直径的影响。

Based on bidirectional backscattering method,Single-mode fiber’s Mode Field Diameter can be simulated by Optical Time Domain Reflectometer.By the change of test conditions,this paper explores the influence of different reference fiber and buffer loss,which is affected in testing Mode Field Diameter through bidirectional backscattering method.
