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.

    ABSTRACT: A numerical study focusing on the feasible upgrade scenario of long-haul undersea optical fiber cable system is discussed. At first, appropriateness of the simulated performance is confirmed through conventional IM-DD modulation format. Then, capacity upgrade of the system is attempted by adopting the RZ-DPSK modulation format. As the RZ-DPSK format alone does not make capacity upgrade possible, additional methods are considered, and the modification of the dispersion map is revealed to be effective. The results show that it is possible to double the capacity of the long-haul undersea system using the RZ-DPSK modulation combined with the dispersion map modification.

    ABSTRACT: Transmission performances of 6,000 km RZ-DPSK system using dispersion flattened fiber (DFF) and non-zero dispersion shifted fiber (NZDSF) were theoretically investigated and compared. Both fibers showed similar performance when the repeater output power was small, but the DFF showed superior performance in the higher repeater output power regime. The result shows that the merit of the DFF is fully utilized when the repeater output power is high enough.

    ABSTRACT: We describe a dispersion management methodology suitable for optimising lumped dispersion compensating schemes in heterogeneous terrestrial optical networks. The technique affords for a significant reduction in time expensive numerical simulations and is demonstrated to be effective for the transmission of 40Gb/s DPSK in representative example networks made up of standard single-mode fibre.
