Paper Abstract

Power propagation equations of multi-pumped fiber Raman amplifier (FRA) is reasonably simplified, multistep average power method is applied to compute composite Raman gain of multi-signals in dense wavelength division multiplexed system (DWDM) amplified by multi-pumped FRA. Based on such a simple and effective model, the influence of the number, input power and wavelength distribution of multi-pumps on Raman gain is researched, the rules to decide their values are reached and the ultra broad and flat Raman gain bandwidth is implemented. All the simulation and analyses supply helpful references for the application of multi-pumped FRA in DWDM system.
