Coherent demodulation of 40-Gbit/s polarization-multiplexed QPSK signals with 16-GHz spacing after 200-km transmission

40-Gbit/s polarization-multiplexed QPSK signals with 16-GHz spacing are demodulated after 200-km transmission by using a homodyne phase-diversity receiver. The highlights of our scheme are electrical post-filtering and digital signal processing that enhance the BER performance.
