摘要
为了延长现有无源光网络(Passive Optical Network,PON)系统的传输距离,本文提出了一种方法,即利用受激拉曼散射增益谱平坦光纤放大器实现对PON系统中光信号的在线放大。通过在PON系统中OLT光模块处注入泵浦光源,采用普通石英光纤放大和掺磷石英光纤进行增益补偿放大的受激拉曼散射增益谱平坦光纤放大器对信号光进行放大,最终实现PON系统光信号的在线放大,从而延长PON系统的传输距离。通过对数据的分析研究,所提出的方法是可以实现PON系统的传输距离延长的。
To prolong PON system transport distance, this paper proposes a method, it is using stimulated Raman scattering flat gain spectrum of optical fiber amplifier to amplify the optical signals in the PON system, online. Through in the system of PON OLT optical module injection pump light, using common silica fiber amplifier and compensate the gain phosphorous quartz optical fiber amplification of stimulated Raman scattering flat fiber amplifier gain spectrum of the signal light amplification, finally realizes the PON system to amplify the optical signal online to extend the transmission distance of PON system. Through the study on the analysis of the data, the proposed method can be extended PON system transmission distance.
