Paper Abstract

Based on analytical methods, we show that when Internet protocol (IP) traffic is loaded directly over differential phase-shift keying (DPSK) wavelength division multiplexing (WDM) systems with perfect dispersion compensation, the burstiness of IP packets has significant effects on the cross-phase modulation (XPM)-induced nonlinear phase noise, and therefore exerts an influence on the packet-error probability performance of the systems. It is demonstrated that the packet-error probability is dependent on the traffic source models. Moreover, we can shorten the packet and diminish the burstiness of the IP traffic to get a small packet-error probability. The results given are helpful for the design of DPSK WDM systems.
