Effect of Optical Filtering on 20-Gbit/s RZ-DQPSK Transmission over 2000 km in a 64-Channel DWDM System

We analyze 20-Gb/s RZ-DQPSK transmission in a 33-GHz spaced 64-channel DWDM system over a 2000-km laboratory straight line. In particular filtering impact on DQPSK modulation format due to optical filter and a de-interleaver at the receiver and pre-filter at the transmitter are experimentally evaluated and commented.
