In the design of optically amplified links for wdm applications , in which the number and power level of the input channels may vary randomly in time as in a network scenario , it is thus essential to stablize the amplifier gain profile 但其增益譜并不平坦,這就要求用于波分復(fù)用系統(tǒng)的摻鉺光纖放大器要有合適的增益、噪聲系數(shù)和輸出功率,還要求增益的動(dòng)態(tài)平衡。
Then research the affect of the system character by the different load stiffness and the relation between load stiffness and the amplifier gain , bring forward a method of adjusting the amplifier gain dynamic to improve the system character 當(dāng)負(fù)載為彈性負(fù)載時(shí),研究負(fù)載剛度的變化對(duì)系統(tǒng)性能的影響和負(fù)載剛度與放大器增益的關(guān)系,提出了一種動(dòng)態(tài)調(diào)節(jié)放大器增益以改善系統(tǒng)性能的方法。
