The dynamical effects of FWM and XPM on optical pulse propagation under IP traffic in dynamical DWDM networks
2008
In this paper, the influence of the burstiness of IP packets on nonlinear effects in dynamical optical Networks such as XPM (cross phase modulation) and FWM (four-wave mixing) are investigated and simulated by adding revised Poisson distributed traffic parameters in the nonlinear Schrodinger equation (NLSE).From simulations, different eye diagrams with different IP traffic loads, different fiber input light powers are achieved. When the input power is bigger than 3 dBm with 40 channels or bigger than 5dBm with 16 channels, the effect of IP bursty traffic could depredates eye diagrams dramatically. The research results are useful for router finding and system design.
