摘要
本文对截止波长的角向滤波测试法进行了理论分析,并与传输功率法进行了比较。文中还介绍了角向测试法的实验装置及对常规单模光纤进行了截止波长测试,测试结果与传输功率法测试结果及矩阵法计算的截止波长基本相符。
In this paper, the detailed theoretical analysis of the azimuthal filtering technique of cut-off wavelength has been carried ont and compared with the communication power method. The experimental set-up and the measurement on the cut-off wavelength of the conventional SM fibers are also described. The results are in fundamental agreement with that of communication power method and the calculation of matrix cut-off wavelength.
