摘要 采用理论分析和软件仿真的方法,研究了级联混合光放大器在超长距波分复用系统中的应用。在讨论单跨距混合光放大器工作原理的基础上,对级联混合光放大器的光信噪比及增益平坦等特性进行分析,设计了适用于ULH系统的高信噪比、动态增益平坦的混合光放大器系统,并结合实际的ULH应用案例进行了建模仿真。 The application of cascading Hybrid Fiber Amplifier (HFA) in Ultra Long Haul systems is studied by theoretical analysis and simulation. Based on discussing the mechanism of HFA, the Gain Flatness and Optical Signal Noise Ratio (0SNR) of cascading HFA is analyzed, designs a HFA with high OSNR and dynamic gain flatness for ULH systems and testified by simulation.
