| 摘 要： | 光纤截止波长是单模光纤的一个重要参数，它与许多因素如模场直径、长度、弯曲、衰减等有关。本文分析研究与截止波长相关的这些因素后，指出在制造光纤光缆时要尽可能减少对光纤截止波长不利的因素，将最小工作波长提高到60－70nm作为设计光纤的截止波长上限，从而有利于降低光纤弯曲损耗。

| Abstract: | The fiber cut off wavelength is a critical parameter for single mode fiber. It is relevant to various factors such as MFD,length,curvature,attenuation etc. The dependence of fiber cut off wavelength is analyzed in this paper. Any unfavorable factor influencing fiber cut off wavelength must be reduced during fiber cable manufacture. The Smallest operation wavelength should be up to 60 70nm,so that it is favorable to decreasing bending loss. |
