TL;DR: In this article, error-free DWDM transmission of 40 40-Gb/s channels with 100 GHz spacing over 10 000 km dispersion-managed fiber using carrier-suppressed return-to-zero differential-phase-shift keying (CSRZ-DPSK), enhanced foward-error correction, and all-Raman-amplified spans with 100-km terrestrial length.

Partial DPSK with excellent filter tolerance and OSNR sensitivity
TL;DR: In this article, it was shown that the tolerance to optical filtering of a DPSK system can be increased by decreasing the differential delay of the traditional MZI-demodulator to less than one bit period.
