摘　　要：合理简化了多泵浦光纤拉曼放大器功率传输方程,利用多步平均功率法进行数值计算得到了密集波分复用系统信号的合成拉曼增益。借助该简化模型研究了多泵浦光源的个数、输入功率和波长分布对信号拉曼增益的影响,简单分析了实现超宽带平坦拉曼增益的多泵浦波配置原则,为多泵浦光纤拉曼放大器在密集波分复用系统中的应用提供了有价值的参考。Power propagation equations of multi-pumped fiber Raman amplifier (FRA) were reasonably simplified, and multi-step average power method was applied to compute composite Raman gain of multi-signal in dense wavelength division multi-plexed 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-pump on Raman gain was researched. The rules of implementing the ultra broad and flat Raman gain bandwidth were analyzed. All simulation and analysis provided valuable references for the application of multi-pumped FRA in DWDM system.
