摘　　要：基于掺铒光纤放大器(EDFA)的增益斜率随着铒纤(EDF)长度变化的实验现象,对EDFA的增益斜率进行了分析,研究了不同EDF长度对EDFA的增益斜率的影响,从理论上对实验现象进行了解释。然后用OptiSystem模拟不同EDF长度下的EDFA增益谱,与实验室增益斜率数据相一致,得出了用EDF的长度来控制EDFA增益斜率的方法。Based on experimental results,different EDF length result in different gain tilt of C-Band EDFA.The gain tilt is analyzed and the experimental phenomena theoretically is explained.Then OptiSystem is used to simulate the different EDF length＇s impact on EDFA gain spectrum.The simulation data and the laboratory data are consistent.So it can draw the conclusion that little change of EDF length plays a great part in EDFA＇s gain tilt.
