研究了色散随机变化对光纤孤子通信容量的影响并给出减少该影响的方法。结果表明,随机色散的存在会使孤子到达时间产生抖动,该抖动与随机色散虚部的均方根成正比,且与孤子的振幅及速度有关;可以引入滤波器来抑制随机色散的影响
The influence of random dispersion of dispersion on the communication capacity of optical fiber solitons is studied and the method to reduce this effect is given. The results show that the existence of stochastic dispersion causes the soliton arrival time to jitter, which is proportional to the root mean square of the imaginary part of stochastic dispersion and is related to the amplitude and velocity of the soliton. A filter can be introduced to suppress the influence of stochastic dispersion
