本文基于多模光纤微弯损耗机理,对光纤结构及涂层属性进行了研究,自行设计了实验方法,对几家公司光纤的微弯损耗作了实验比较,在分析实验结果的基础上为改善多模光纤的微弯及低温性能提出了自己的见解。
In this paper, based on the microbend loss mechanism of multimode fiber, the properties of the fiber structure and the coating are studied. The experimental methods are designed by ourselves. The microbend loss of several optical fibers is experimentally compared. Based on the analysis of the experimental results, Multi-mode fiber micro-bending and low temperature performance put forward their own views.
