【摘要】 本文研究ＡＭ－ＳＣＭ系统中饵光纤放大器的非线性失真及其对系统性能的影响。分析计算了信号激光器频率啁啾和ＥＤＦＡ增益斜率之间相互作用及失真随输入信号光功率的变化，最后讨论了降低这种失真的方法。更多还原

【Abstract】 The noninear distortion induced by erbium-doped fiber amplifier in AM-SCM system andits influence to system properties are investegated.First,the interaction between the frequency chirp-ing of the light source and the wavelength dependent gain slope of the EDFA is analyzed, then the dis-tortion varing with input signal power is calculated,At last,ways to improve this kind of distortionare discussed.更多还原
