Influence of filter shape and bandwidth on 44 Gb/s DQPSK systems

Filter shape and bandwidth are studied for multiplexers/demultiplexers in DQPSK systems. Simulation shows both factors have strong impact on signal performance. In 50GHz spaced systems with 44Gb/s RZ-DQPSK signals, 2nd-order super-Gaussian filters outperform higher-order filters.
