Numerical Estimation of Phase Jitter in a Dispersion Managed Link

摘要：

The detailed origin of phase jitter in fiber-optic communication systems was firstly reviewed. An overview of distribution of received phase jitter was presented. By contrasting the phase difference of sample pulses, variance of phase noise of an DPSK system in dispersion-managed finite fiber spans was calculated and simulated by Matlab, and the Gaussian shaped possibility density function (p.d.f.) was obtained. The performance of signal was analyzed by estimating BER, which was calculated from the p.d.f.. By adding ASE noise of different power into the signal at each EDFA, we found that the suppression of ASE noise contributing considerably to the improvement of signal performance.
