摘　　要：该文首次在同时考虑3种高阶效应和孤子互作用的条件下,应用变分法,导出了孤子各特性参数随传输距离的演化方程,基于此方程应用线性扰动法,从理论上导出了稳定性条件,论证了160 Gb/s高斯准孤子系统零频移稳定传输的可行性,并设计出一个比特率为160 Gb/s高速长距离孤子通信系统,对其性能进行数值模拟仿真,其结果和理论分析一致。In this paper,the evolution equations of solitons＇ performance parameters versus distance are deduced by the use of the variational approach under the condition of both the higher-order effects and interaction between solitons for the first time.Based on this equation,a stable operation condition is revealed from theoretical analysis by using a linearization perturbation method.It is discovered that the stable transmission of the Gaussian quasi-soliton system with zero frequency shift at bit rates up to 160 Gb/s can be realized.A 160 Gb/s high-speed and long-haul soliton transmission system is designed and its performance is numerically simulated.The simulation results are in well accordance with the theoretical analysis.
