A theoretical study focusing on the effect of zero-crossing points in the dispersion map for the long-haul return-to-zero differential phase shift keying (RZ-DPSK) transmission system had been conducted. Difference of the transmission performance was characterized with regard to number of zero-crossing points within the dispersion map. It was observed that increasing the number of zero-crossing points in the dispersion map combined with the self phase modulation (SPM) caused the performance degradation near the system zero dispersion wavelength.
