摘要
当弯曲不敏感单模光纤(G.657类光纤)应用后,其截止波长在测试中经常会出现测试值偏大或测不出等"新"问题。本文试图通过探讨G.657类光纤的原理和截止波长的物理意义,以及分析测试的中间数据,来挖掘和解释这些问题的根本原因。
After the application of bend-insensitive single-mode fiber （G.657 class fiber）, some ＂new＂ problem occurs： the test results of cut-off wavelength test are sometimes too large or could not be determined. This paper attempts to explore the principle of the G.657 class fiber and the physical meaning of the cut-off wavelength, and the analysis of the in process data during the test, to excavate and interpretate the root causes of these problems.
