摘　　要：基于光脉冲在光纤中传输所遵从的NLS方程,采用对称傅里叶数值方法计算了不同因素引起的孤子互作用对其传输特性的影响。结果表明,孤子间隔、孤子间的相差以及两孤子的振幅比都是影响光孤子相互作用极其敏感的因素。本文同时引用实验数据计算了高阶色散对孤子互作用的影响,并针对各种因素提出了相应的解决方案,这对实际光孤子通信具有指导意义。Based on the NLS equation with which the light pulses comply when transmitting in the optical fibers, the transmission characteristics of the soiitons are studied by symmetric Fourier numerical method. Different factors that cause interaction between the solitons are analyzed. The results show that the interval, phase difference and the ampli- tude ratio of the soliton pair are the extremely sensitive factors to affect the interaction of optical solitons. At the same time, the experimental data is introduced to calculate the influence on soliton interaction by high-order dispersion, and the corresponding solutions are given for a variety of factors. It offers reference value for actual optical soliton commu- nication.
