本文采用变分法研究 WDM 与 OTDM 复用系统中色散管理孤子各参数的动态演化行为,同时给出了在强、弱色散管理条件下,扰动系统的脉冲参数的统一解析表达式通过这些方程组.就可以给出色散管理孤子的脉冲能量随传播距离的演化关系、孤子因扰动而产生的定时抖动大小以及色散管理强度大小对这种定时抖动的抑制关系,从而达到优化色散管理孤子方案
In this paper, the variational method is used to study the dynamic evolution of the dispersion management soliton parameters in the WDM and OTDM multiplexed systems. At the same time, the uniform analytical expressions of the pulse parameters of the perturbation system are given under the condition of strong and weak dispersion management. . The relationship between the pulse energy of dispersion management solitons and propagation distance can be given, the timing jitter caused by the disturbances of the solitons and the suppression of the timing jitter by dispersion management intensity can be achieved, so as to optimize the dispersion management soliton scheme
