Transmission of 112Gb/s PM-RZ-DQPSK over 960 km with adaptive polarization tracking based on power difference

Abstract

All-optic scheme for polarization multiplexed system de-multiplexing were implemented with high-speed and precise optical polarization tracking based on power difference. Stable polarization demultiplexing with 800rad/s polarization scrambling for 112Gb/s direct detection PM-RZ-DQPSK transmission over 960km was demonstrated.
