摘要
本文讨论了空气隙型光固定衰减器的回波损耗。从理论上分析了输入端界面折射率失配、空气隙的长短这两个主要因素对衰减器回波损耗的影响,并通过实验进行了验证。
This paper discusses the return loss in air-space type fixed optical attenuator. Theoretically, we analyzed some influences over the return loss of this kind of attenuator, which are mainly caused by the refractive index discontinuity at the input boundary and the length of air space,and also, we have demonstrated by means of experiments.
