摘要
介绍了掺铒光纤放大器的黑盒模型 ,随后给出应用黑盒模型的参数测量步骤 ;测量了一台内部参数和结构未知的商用 EDFA对六信道 WDM光信号的放大光谱图。通过实测结果与黑盒模型仿真计算得到的结果相比较 ,证明了黑盒模型具有很好的精度 ,适用于估算商用波分复系统的性能。
A black box model of Erbium-doped fiber amplifiers is introduced in this paper.The measurements setup to record the data for using black box model are presented.Six WDM channels were fed into a commercial EDFA whose internal optical circuitry and parameters are unknown.Comparison between the measured amplified optical spectrum and the spectrum computed by black box model demonstrated the black box model's accuracy and value for estimation of practical amplified WDM systems performance.
