摘　　要：　光纤色散和非线性是影响密集波分复用(DWDM)系统性能的主要因素。高阶色散管理技术,可以有效地减小四波混频(FWM)和信号波形失真。介绍了该技术的基本原理及不同色散分布方法对系统性能的影响。Fiber dispersion and nonlinearity are two main factors limiting the performance of dense-wavelength division multiplexing (DWDM) transmission systems. In order to reduce the four-wave mixing (FWM) crosstalk and avoid the signal waveform distortion, the higher-order dispersion management techniques are proposed. At the same time, the influence of different dispersion arrangements on the systems' performance is introduced.
