The soliton transmission system has great potential for providing high speed and long distance communication. However, the polarization-mode dispersion (PMD) of fiber becomes a serious limitation when the bit-rate of systems is over 40 Gbit/s. So it is very urgent to study the influence of PMD on the Soliton communication system.
In this paper, we use numerical simulations to calculate the Nonlinear Schrodinger Equations with the PMD effect. In our simulation, we mainly investigate the transmission properties of the Manakov-soliton in optical fibers with PMD at the wavelength of 1550 nm. We discuss the self-trapping effect for a single pulse of Soliton, which can prevent a soliton pulse with PMD from splitting. Then we take the pulse sequences into account, which is more significance in real transmission link, we discuss the timing jitter problem due to the loss of Soliton energy.
