摘要
根据掺铒光纤放大器(EDFA)两能级放大模型推导出黑盒模型(BBM,black box model),随后给出了黑盒模型的通用测量步骤及注意事项。该模型基于EDFA的外特性,运算速度快,同时考虑了EDFA的饱和、增益不平坦特性以及ASE噪声谱的非均匀性。它对于在现场实验前仿真和分析系统性能具有较高的实用价值.
The black box model for an Erbium-doped fiber amplifier(EDFA) was derived from the two-level amplified model,and the general measurements setup to record the data and measurement cautions for using the black box model were presented.The model based on the exterior character of EDFA has fast operation and also considers the saturation,uneven gain character and non-uniform amplifier spontaneous emission noise spectrum character of EDFA.The model has high practical value for simulation and analysis of systems performance before real experimentation.
