摘　　要：对多泵浦光纤喇曼放大器 (FRA)功率传输方程进行了合理简化 ,得到密集波分复用系统 (DWDM)信号合成喇曼增益的数学模型 ,分析了受激喇曼散射 (SRS)对信号喇曼增益的影响。并在该简化模型基础上介绍了一种对泵浦波长分布和输入功率进行优化计算的方法 ,实现了超宽带平坦的喇曼增益谱 ,为多泵浦FRA在DWDM系统中的应用提供了有价值的参考。Power propagation equations of multi-pumped fiber Raman amplifiers(FRA) are reasonably simplified,a mathematical model of composite Raman gain of multi-signals in dense wavelength division multiplexed system (DWDM) amplified by multi-pumped FRA is built,and the influence of stimulated Raman scattering (SRS) on Raman gain is analyzed.Based on such a simple and effective model,an algorithm to optimize pump wavelength distribution and input power is introduced and the ultra broad and flat Raman gain spectra are implemented.All the simulation and analyses supply valuable references for the application of multi-pumped FRA in DWDM system.
