【摘要】 在以太无源光网络(EPON)系统中,光线路终端(OLT)和光网络单元(ONU)之间的最长光纤传输距离为20km,但在某些光纤到村(FTTV)之类的应用中,光纤线路的距离达到了80km甚至更远。文章提出了一种延长EPON系统传输距离的方法,它实现了一种适用于EPON系统的光功率放大器,且对EPON的注册发现窗口,上行带宽分配周期等参数进行了调整。更多还原

【Abstract】 The maxium fiber distance between OLT and ONU in EPON system is 20km, but in some application scene such as FTTV(Fiber to the village), the fiber distance can reach 50Km or even longer, A methodology of extending the transmission distance for EPON system is proposed in this paper, which includes the optical power amplifier and the adjustment of DBA.更多还原
