在介绍BPON系统的网络分层结构基础上,分析了光网络终端(ONT)设备实现的主要功能,讨论了实现方案。
After introducing the layered structure, principle of BPON, analyzing the main function of ONT, the hard ware designing process is discussed.
由于不同的光网络单元onu与光线路终端olt的距离不同,实际工作时到达接收端的信号的幅度,相位都相差很大。
Because the distances from different ONUs to OLT are different, the amplitudes and phases of the different signals will have significant difference when receiving the receive terminal.
