Nonlinear Polarization Scattering Impairments and Mitigation in 10-Gbaud Polarization-Division-Multiplexed WDM Systems
01 January 2009
Transmission experiments on 10-Gbaud polarization-division- multiplexed (PDM) DQPSK, DBPSK and OOK show that time interleaving return-to-zero signals in two polarizations can significantly reduce nonlinear polarization scattering in PDM WDM systems and increase system tolerance to inter-channel nonlinearities.
