摘　　要：研究了基于G.653光纤的C波段密集波分复用传输系统中的波长配置方法,推导出了包含光放大器的多段光纤链路的四波混频(FWM)产物功率的解析表达式,引入了粒子群优化算法解决波长配置问题,同时得到了可行的16波信道配置方案.同已有的方法相比,粒子群优化算法支持的信道数更多(>=16),四波混频效应得到了较好的抑制,系统性能明显得到提高.Based on the particle swarm optimization （PSO） algorithm, a novel FWM power estimation method was proposed. And a technique to design the channel frequency allocation in order to minimize the crosstalk due to FWM in optical dense-wavelength-division multiplexing （DWDM） systems was presented. Which is able to support unfixed fiber dispersion parameters along the links and arbitrary span configuration and more than 16 channels frequency allocation. An effective 16 channels allocation method was obtained,and was compared with other similar methods. The result shows that it can restrain FWM effect much more significantly.
