Abstract :
We provide a whole scheme design of the DSP part for POLMUX-NRZ-DQPSK coherent receiver, in which the adoptive algorithm of each module and preferred parameter value of algorithm are discussed. Finally, we demonstrate 8×112Gbit/s DWDM transmissions with a 50GHz channel-spacing over 2000km of SSMF by using the digital coherent receiver.
