The most important feature of Raman gain spectrum is that the gain peak wavelength only depends on the pump wavelength (fixed shift about 100nm). Using the gain values of these gain peak wavelengths we can determine how to adjust power and intervals of pumps until the optimal result is made. In this paper, using the peak wavelength gain optimal method and a comprehensive model the Raman gain spectra of multi-pumped FRAs under the various conditions were investigated. The results show that controlling the pump sources power and wavelength intervals can optimize the bandwidth and flatness of gain spectrum. The optimal configuring method for the multi-pump sources of distributed FRAs is simple and effective.
