Abstract :
Digital signal processing is a key feature in coherent dual polarization QPSK optical transmission, and plays an essential role to determine system performance. In this paper, we present a set of signal processing algorithms able to recover a single channel 112 Gb/s DP-QPSK signal after 3000 km propagation in a recirculation loop. The OSNR resilience and optical filtering impact over maximum reached distance were also investigated.
