摘　　要：提出了一种基于单波长的智能化掺铒光纤放大器结构方案,并进行了相关仿真研究。该掺铒光纤放大器通过控制若干个1×2光开关选择对于不同输入光信号功率所需要的最佳铒纤长度,结合泵浦功率的调节,可以得到最优的增益和输出光信号功率。仿真实验表明该放大器可以达到较好的性能,既可以作为功率放大,也可以用作前置放大和线路放大。An intelligent erbium-doped fiber amplifier （EDFA）based the single wavelength is proposed and relevant simulation experiments are demonstrated. The amplifier controls several 1 × 2 optical switches to select the optimum erbium-doped fiber length for the different input signal power, combined with the modulation of pump power, high gain and output signal power could be acquired. Simulation experiments have demonstrated that this amplifier can get high quality. This amplifier can be applied as preamplifier and line amplifier as well as power amplifier.
