The methods and the experimental setups for measuring the gain and noise figure of an edfa are emphasized. we introduce how to measure the characteristics of each component of an edfa, especially the gain and absorption coefficient of an erbium doped fiber ( edf ). thirdly, four types of simple and novel l - band edfa structures with low noise, high gain and low gain ripple are proposed to satisfy the requirement of a dwdm system
基於考慮自發輻射噪聲（ ase ）的giles模型，建浙江大學博士學位論文立了這種edfa的全光增益箱制理論模型;理論和實驗分析了四種可能的光路結構、泵浦波長、光纖光柵反射波長和反射率、泵浦功率以及摻餌光纖長度等參t對其箱制特性的影響。 -

In addition, the performance criterion is respectively described, and the torque ripple at low - speed is analyzed in this paper. according to a method to adjust the duty ratio coefficient, we select a torque track with adaptation fuzzy controller to simulate. the experimental results show that the control strategy proposed can acquire better control effect
針對直接轉矩控制系統在低速運行時依然存在的轉矩脈動大、運行性能差的問題進行研究分析，結合傳統的固定采樣周期控制方法，提出一種基於自適應模糊轉矩跟蹤法，調節電壓矢量占空因子，進行模擬研究，改善了系統的低速性能。 -
On the other hand the crosstalk of the wdm signal at fan - out of demultiplexer will increase with the power difference of the each channel. therefore, the gain of optical amplifier to wdm signal must have small ripple. one of the solutions is using two or more pumps with different wavelength and power according to the range of signal light to be amplified and raman gain coefficient of the fiber
另外，各路信號光之間較大的功率差異會增加wdm通道解復用器輸出端的串話，所以光放大器對wdm各路信號光的增益要滿足一定的增益平坦度，解決該問題可以根據所要放大的wdm信號光的波長范圍和所用光纖的拉曼增益系數譜，採用多個不同波長和功率的泵浦光源進行泵浦。
