摘　　要：提出了一种基于光纤中四波混频(FWM)效应实现对光信号的再放大和再整形的2R再生功能的方法,分析了该方法的工作原理,设计了一种基于光纤FWM效应实现光信号2R再生的光纤传输仿真系统。仿真结果表明,2R再生信号良好,系统Q值达到21.59,验证了该方法的可行性。所设计的2R再生方案中,泵浦光的波长与功率是影响FWM效率和2R再生性能的主要因素,对其进行了扫参研究,得出泵浦波长为1 548nm、功率为40dBm时,2R再生性能最优。A method for re-amplifying and re-shaping optical signal based on four-wave mixing effect(FWM)in fiber is proposed to realize optical signal 2 R regeneration,and the working principles of this method are analyzed.An optical fiber transmission simulation system based on FWM effect to realize 2 R regeneration of optical signal is designed.Simulation results show that,the 2 R regeneration signal is good and the system Q value is up to 21.59,which verifies the feasibility of the proposed method.The wavelength and power of pump light are the main factors affecting FWM efficiency and regeneration performance.The optimal performance of the system is obtained when the pump wavelength and power is 1 548 nm and 40 dBm,respectively.
