摘　　要： 给出了设计波分复用 (WDM)用高增益、低噪声和宽带宽增益平坦的双段级联掺铒光纤放大器 (EDFA)的一般步骤和方法 通过优化设计各种参量 ,研制出了一台高增益、低噪声和宽带宽增益平坦的双段级联EDFA样机 ,实现了从 15 2 4 .8～ 15 6 1.4nm共 36 .6nm带宽内± 0 .32 5dB的平坦增益 ,0dBm输入时 ,饱和输出功率大于 15dBm的高功率输出 ;噪声指数低于 The method and processes for designing high-gain, low-noise and gain-flattened with wide bandwidth two-stage erbium-doped fiber amplifier (EDFA) using for wavelength division multiplexing (WDM) system are given. By optimization of EDFA parameters, a high-gain, low-noise and gain-flattened with wide bandwidth two-stage EDFA was developed and achieved. The EDFA has a ±0.325 dB flattening gain in 36.6 nm bandwidth from 1524.8 nm to 1561.4 nm, a high output power more than 15 dBm when 0 dBm 1550 nm signal is input and a noise figure lower than 5 dB.
