title = "Performance of optical DPSK and DQPSK in 40G bit/s transmission systems",
abstract = "We have simulated the OSNR sensitivity, filtering tolerance, chromatic dispersion tolerance, and nonlinear tolerance of optical DPSK and DQPSK formats with and without RZ carving in 40Gbit/s transmission systems. The results show that RZ-DPSK has the highest OSNR sensitivity, and is most robust against fiber nonlinearity in dispersion compensated systems with moderate channel spacing. The DQPSK systems have the highest filtering tolerance and dispersion tolerance, and is least affected by the reduction of the channel spacing. The simulations of long haul dispersion compensated systems show that RZ-DPSK has better performance in single channel system and WDM system with 100GHz channel spacing, while RZ-DQPSK has better performance in WDM system with 50GHz channel spacing.",
