32-krad/s polarization and 3-dB PDL tracking in a realtime digital coherent polarization-multiplexed QPSK receiver

32-krad/s polarization and 3-dB PDL tracking in a realtime digital coherent polarization-multiplexed QPSK receiver

The tolerance against fast polarization changes and PDL of a digital coherent QPSK receiver is determined in a 2.8 Gb/s realtime polarization-multiplexed transmission experiment. The sensitivity penalty for polarization changes with a speed of 32 krad/s on the Poincare sphere is 0.5 dB.
