针对级联放大WDM系统中动态增益失衡的问题,通过全光和光电混合方法控制粒子数反转水平,自行设计制作出了动态增益均衡掺铒光纤线路放大器和功率放大器,并通过8×25Gb/s450km传输实验,证明了这种放大器对系统动态变化的均衡作用
Aiming at the problem of unbalanced dynamic gain in cascaded WDM system, the dynamic gain equalization of erbium-doped fiber line amplifiers and power amplifiers is designed and manufactured by using the all-optical and opto-electronic hybrid method to control the inversion level of particles. The 8 × 25Gb / s450km transmission experiment proves that this amplifier has an equalizing effect on the dynamic change of the system
