Impact of dispersion map design upon transmission performance of long-haul RZ-DPSK system using dispersion flattened fiber.

This paper describes a theoretical study of the impact of dispersion map design upon the long-haul RZ-DPSK system using the dispersion flattened fiber. Numerical simulations are conducted to clarify the transmission performance of different dispersion map designs. As a result, number of dispersion blocks has a significant impact upon the transmission performance, and reduction of the number improves the nonlinear tolerance of the system.
