Abstract :
We demonstrated adaptive optical compensation for DGD, using the Pseudo-Return-to-Zero modulation scheme, without the disadvantages of polarization scrambling. We verified a compensation range of 71.8ps (2UI) for 112G PRZ-DP-DQPSK signal and validated the compensation over 610km transmission.
