摘　　要：简要分析了色散管理孤子的基本原理和特性,并通过数值计算对色散管理孤子传输过程中的孤子互作用进行了模拟。发现在色散管理光纤链路中,如果平均色散与本地色散差异较小,色散管理孤子最好取双曲正割形,孤子互作用表现为非线性互作用;如果本地色散和平均色散差异逐渐变大,色散管理孤子波形向高斯形变化,色散逐渐成为影响孤子互作用的主要原因。Properties of dispersion-managed soliton are analyzed. Dispersion-managed soliton propagation and interaction in optical fibers are numerically simulated. If there is little difference between local dispersion and average dispersion, it is better to insert the pulse with shape as hyperbolic secant. If increasing the differences of local dispersion and average dispersion, the shape of the pulse will transform as Gaussian. Dispersion become the main factor of dispersion-managed soliton interaction.
