GPON是一种应用于接入网、局端设备(OLT)与多个用户端设备(ONU/ONT)之间,通过无源的光缆、光分/合路器等组成的光分配网(ODN)连接的网络,在OLT(光线路终端)和ONU(光网络单元)之间的ODN(光分配网络)没有任何有源电子设备。文章针对什么是GPON技术及GPON的硬件结构作了简要介绍,并分析了GPON常见故障的处理方法。
GPON is an optical distribution network (ODN) that is applied to the access network, the office terminal equipment (OLT) and multiple client devices (ONU / ONT) through a passive optical cable, optical splitter / combiner and the like ) Connected network, the ODN (Optical Distribution Network) between the OLT (Optical Line Terminal) and the ONU (Optical Network Unit) does not have any active electronic equipment. The article gives a brief introduction of what is GPON technology and the hardware structure of GPON, and analyzes the processing methods of GPON common faults.
