Abstract :
We demonstrate a precise skew monitoring between multiplexed polarizations, demultiplexed polarization discrimination and large-PMD tolerance enhancement for 110 Gbit/s PolMux-QPSK signal, by introducing a new modulation scheme, pseudo-return-to-zero, and using the information it carries.
