具有滑频滤波器的光孤子通信系统时间抖动的研究

Studies on Timing Jitter of Soliton Transmission with Sliding Filters

本文通过微扰理论，对采用滑频滤波器控制的孤子系统的时间抖动进行了研究。结果表明，滑频滤波器的引入，导致幅度和频率、幅度和滑频滤波器三阶项间的耦合，使得孤子传输系统的时间抖动增大，影响系统的传输极限。研究了滑频滤波器三阶项对滑频速率的影响，讨论和比较了具有滑频滤波器、固定频率滤波器和不加任何控制时的系统对由放大器的ＡＳＥ噪声产生的时间抖动的抑制结果。采用滑频滤波器是一种较好地抑制时间抖动的方法。

In this paper,timing jitter in soliton transmission with sliding filters is studied by the firs torder perturbation theory The results show that the couplings both between amplitude and frequency fluctuations and between amplitude and three order filter term that is due to sliding filters enhance timing jitter We have researched the effect of three order filter term on the sliding rate We discuss and compare the suppression of timing jitter induced by amplifier ASE noise with sliding filters or bandwidth filters or no soliton transmission control It is a better scheme to reduce timing jitter by sliding filter
