| 摘 要： | 针对多信道放大时掺铒光纤放大器（ＥＤＦＡ）的增益谱随饱和深度而变化的现象，本文介绍了ＥＤＦＡ增益谱在等效饱和条件下的双波长和宽谱光源迭代测试法及等效饱和信号功率的计算公式．使用这种方法只需少数几次迭代即可准确测出当ＥＤＦＡ应用于波分复用系统时各信道的实际增益，实验测得结果的误差不大于０１５ｄＢ．

| Abstract: | Because the gain spectrum of an Erbium doped fiber amplifier (EDFA) varies with the saturation level,an iterative method of measurement on multichannel gain spectrum under equivalent saturation by using dual wavelength or broadband signal is introduced and the power of the equivalent saturation signal is derived.Only several iterations are required to reach enough accuracy.The error of the experiment is no greater than 0.15 dB. |
