摘　　要：为了抑制四波混频FWM效应,根据其产生机理和主要影响因素,结合信道的合理分布,文章设计了3种基于传统信道等间隔系统的改进方案,并与传统方案进行了比较,分析了每种改进方案的性能特点,以及在每种方案下传输距离对系统性能的影响。文章采用optisystem软件搭建系统信道模型,并进行了仿真研究。结果表明改进方案都能很好地抑制FWM效应,且后两种方案的效果更好,能有效提高系统的性能。In order to suppress the four-wave mixing FWM effect,according to its generation mechanism and main influencing factors,combined with the reasonable distribution of channels,three improved schemes based on the traditional channel equal interval system are designed,and compared with the traditional scheme,each is analyzed improve the performance characteristics of the scheme and the influence of the transmission distance on the system performance under each scheme.The system channel model was built using optisystem software,and simulation research was carried out.The results show that the improved scheme can restrain the FWM effect well,and the latter two schemes have better effect and can effectively improve the performance of the system.
