摘　　要：掺铒光纤放大器(EDFA)的增益平坦化是密集波分复用(DWDM)系统中的关键问题,通过对比、分析增益平坦滤波器(GFF)的模拟和实验两种谱线的设计及修正方法,认为实验的方法是较好的选择。通过试验,大量数据表明用桌面实验测得的Gain Error谱线与模拟的GFF谱叠加,可得到比模拟更好的GFF设计谱线。EDFA＇S gain flattening is the key issue in the DWDM system, Through comparative analysis two kinds of simulation and experimental spectrum correction method of GFF in the paper,and considered experi- mental method is a better choice. After the test, a large number of data indicates gain Error spectral line with this GFF spectrum line overlay, can get a better design spectral line than analog spectral lines.
