Performance Limitations of 40-Gb/s RZ-DPSK DWDM Systems Due to Nonlinear Effects and Their Mitigation

M. Arafat Rahman Khan, Tahsin Faruque, and Mohammad Faisal
Abstract—Performance of 40-Gb/s return-to-zero differential phase-shift keying (RZ-DPSK) dense wavelength division multiplexed (DWDM) systems is evaluated numerically. The quality factor Q is measured at the receiving end of the dispersion-managed (DM) transmission line. The performance margin due to fiber nonlinear effects like cross-phase modulation and four-wave mixing has been investigated. The mitigation technique for these nonlinear effects has also been explored with satisfactory results.

Index Terms—Cross-phase modulation (XPM), dispersion management, DWDM, four-wave mixing (FWM), RZ-DPSK.
