Impact of Polarization Mode Dispersion on Transmission Characteristics of Dispersion-Managed Solitons and Its Suppression

The coupled nonlinear Schrödinger equations for dispersion-managed soliton (DMS) with the impact of the polarization mode dispersion (PMD) are constructed, and a PMD-suppression approach of DMS is proposed for the first time. Then, based on variational method, the analytical equations of the DMS transmission system with in-line optical filter control are obtained. Finally, in order to investigate the validity of the equations, we present an application sample for practical systems with in-line filter control. The results verify that the control is quite effective and valid.
