The numerical method to calculate the signal and pump interaction in back pumped fiber Raman amplifier is present. By the method, the evolution of signals and pump along the fiber can be obtained. The spectral characteristic of multi channel DWDM transmission systems can also be known. Simulation results are demonstrated for the cases of single channel and 40 channel transmission with back pumped fiber Raman amplifier in DWDM transmission systems. The numerical method presented is rigorous for the depletion of pump because signal amplification is included. It is useful for the design, analysis and application of back pumped fiber Raman amplifiers.
