摘要：

Tolerance to optical filtering of a DPSK system can be increased significantly by decreasing the differential delay of the traditional MZI-demodulator to less than one bit-period. It is shown that a 43 Gbit/s DPSK signal can support 50 GHz channel spacing if the delay is decreased to 65% of a bit-period.
