摘要
首先根据 EDFA两能级放大模型推导出黑盒模型 ;其次 ,采用虚拟实验方法 ,分析了黑盒模型在不同条件下计算的精度 ;最后分别模拟放大系统采用黑盒模型和两能级模型 ,有八个 WDM光信号输入时 ,放大后的光谱图 .结果表明两者十分一致 .
In this paper,first,the black box model for an erbium doped amplifier was derived from the two level amplified model.Then adopting the so called virtual experiment,it is analyzed the computation accuracy of the black box model in verified conditions.Finally,when there were eight WDM optical input signals,using the black box model and two level model respectively,we simulated the amplified optical spectrum.The results agreed with each other very well.
