Abstract Based on a hybrid genetic algorithm, the bandwidth for distributed multi-pump Raman amplifier (DMRA) is optimized. Optimal results show that signal bandwidth Δλ can be evidently broadened by means of increasing the number of pumps, Δλ decreases with the increase of Raman gain and with the improvement of flatness property, and the hybrid erbium-doped fibre amplifier and DMRA can availably overcome the weakness of pure DMRA.
