摘　　要：为了分析光路参数对反向泵浦掺铒光纤放大器(EDFA)增益的影响,采用OptiSystem软件建立了反向泵浦EDFA的系统仿真模型。通过分别将泵浦功率和铒纤长度设置为“Sweep”模式,分析了泵浦功率、铒纤长度和信号功率对放大器增益的影响。仿真结果表明,泵浦功率越高,放大器增益越大,但增大的速率逐降低。EDFA增益随掺铒光纤长度呈现先增加后减小的趋势,存在一个获得最高增益的铒纤长度。信号功率较小时,放大器可实现较高的增益,信号功率增大时,放大器的增益值逐渐减小,出现增益饱和。In order to analyze the influence of optical parameters on the gain of back-pumped erbium-doped fiber amplifier(EDFA),the simulation model of reverse pumped EDFA is established using OptiSystem software.By setting the pump power and erbium fiber length to"sweep"mode,the effects of pump power and erbium fiber length on the gain of the amplifier are analyzed.The simulation results show that the higher the pump power is,the greater the amplifier gain is,but the increasing rate decreases gradually.EDFA gain increases first and then decreases with increasing the length of erbium-doped fiber,and there is an erbium fiber length with the highest gain.When the power of signal is low,the amplifier can achieve higher gain.The gain value of the amplifier decreases gradually as the signal power increases,and the Gain saturation occurs.
