弯曲损耗不敏感单模光纤宏弯谱损耗测试分析

Measurements of macrobend spectral loss for bend insensitive single mode fiber

本文通过实验的方法分析比较了G.657光纤宏弯性能测试中可能的Whispering gallery modes在不同测试条件下对测试结果的影响,报告了在宏弯损耗测试中根据需要采用绕多圈方法以增强宏弯损耗测试的响应效果,以减小Whispering gallery mode对测试结果影响的方法。

In this paper, we analyzed the Whispering gallery modes influence to spectral macrobending loss of G.657 fiber under different test deployment at small bend radius and introduced the use of additional multiple wraps to increase the macrobending response which also abated the Whispering gallery modes influence.
