Abstract

Differential phase-shift keying (DPSK) has recently attracted a great deal of attention especially for high-speed, long-haul transmission systems. The reason is that, compared to conventional on-off keying (OOK), this format offers ~3 dB better receiver sensitivity and higher tolerance to some fiber nonlinearities. To take full advantage of this modulation format, however, balanced reception should be provided for the receiver, which makes the system implementation complex and costly. This paper reviews the recent progress of DPSK format, with emphasis on system impairments by linear and nonlinear optical phenomena. We also compare the merits and demerits of DPSK with those of OOK format.
