Analysis of dynamic gain equalization in dwdm 系统中的应用分析
三 . dynamic gain equalizer ( dge ) based on volume phase grating ( vpg ) . edfa ' s gain spectrum has dependence on the edfa ' s operate point Edfa在不同的工作状态具有不同的增益谱,这就要求增益补偿器件的增益谱形状要随edfa工作状态的不同而发生变化。
Economic gets considerably dynamic gains from trade of our country . that is to say , our country ' s foreign trade grows quickly and promotes economic growth strongly after our country ' s reform and opening 改革开放以来,我国经济从快速增长的国际贸易中获取了较大的动态利益,即我国的国际贸易对经济增长起到了重要的拉动作用。
The method of dynamic gain equalization based on the temperature and bending characteristics of the novel lpfg was demonstrated . another method based on the temperature and transverse load characteristics was also demonstrated . the resonant amplitude and wavelength of the lpfg were adjusted by applying bend or transverse load and temperature to the lpfg , respectively Ii .利用新型长周期光纤光栅进行了edfa的动态增益均衡,根据新型长周期光纤光栅的可调谐性,提出了一种基于新型长周期光纤光栅的温度及弯曲特性的动态增益均衡器,并介绍了另外一种基于温度及横向压力特性的动态增益均衡器。
A dynamic gain equalizer device including control circuit , mechanical structure and control program was designed using a cooler and a pzt . a dynamic gain equalizing experiment of the edfa using the designed dynamic gain equalizer was accomplished , and a 1 . 2db flatness in the range of 32nm at c - band was obtained . finally , some future improvements were discussed in this Iv .设计了一种利用制冷器和压电陶瓷等来实现动态增益均衡器的装置,设计了控制电路、机械结构和算法程序,用这个动态增益均衡器对edfa的增益输出谱线进行了动态增益实验,实验结果基本满足要求,根据实验结果,文中还讨论了一些改进方案。
