摘要
众所周知,光纤的涂覆性能、包层不圆度、模场直径以及光纤的弯曲损耗都会对光纤的传输性能产生影响。其中光纤的弯曲损耗是对光纤的传输性能和传输功率产生影响的重要参数之一。因此针对光纤弯曲损耗的研究对光纤的实际应用有非常重要的意义。简要分析了光纤弯曲时芯区折射率的变化与弯曲损耗的对应关系;其次对单模光纤的弯曲损耗进行了理论研究,将光纤的弯曲半径对光纤弯曲损耗的影响进行分析总结,从理论上进行研究,得出两者的相关性,对以后的工作具有一定的借鉴意义。
It is well known that coating performance of optical fiber,roundness of cladding,field diameter and bending loss of light have an influence on the transmission performance of optical fiber. Bending loss of fiber is one of the important parameters that affect the transmission performance and transmission power of fiber. Therefore,the study of bending loss of optical fiber is very important for the practical application of optical fiber. In this paper,the influence of refractive index of the core on bending loss was analyzed. Secondly,the bending loss of single-mode fiber and the panda-type polarization maintaining fiber were studied theoretically. The relevance of the two was obtained,which has some reference forfuture studies.
