摘　　要：波分复用系统对掺铒光纤放大器增益的动态平坦提出了严格的要求,为此人们设计了各种动态增益均衡器以实现EDFA的增益谱的平坦化。现有的各种动态增益均衡技术分静态和动态两种。我们讨论了几种不同类型的动态增益均衡方法,详细并举例分析几种典型的动态增益均衡器基本结构、工作原理、适用范围及其优缺点。最后对未来动态增益均衡器的发展作了展望。Wavelength Division Multiplexing (WDM) network puts stringent requirements for control of spectral dependence of optical amplifier gains. Dynamic and static equalizers are two ways to realize the gain flattening of EDFAs. Hence, we discussed the various technologies available for dynamic gain flattening and described the basic scheme and operation principle of several prevalent dynamic gain equalizers. In the end, we expected the future development of dynamic gain equalizers.
