摘要：

PON规模运营后，由于其多用户共享上行带宽的技术特性，使得异常发光ONU成为网络运营中的凸显故障。本文主要介绍现网中发现的典型故障，分析异常发光ONU的产生原因，并且结合实际网络运维经验，对 PON 设备能力提出了技术要求，提出了适用于现网的异常发光 ONU 的检测机制和流程。

Abstract:

Abnormal light emitting ONU is a critical failure in PON due to the nature that more than one subscribers share PON upstream bandwidth,especially in mass deployment of PON.This article describes the typical phenomenon in real network and analyses the root causes that ONU launch abnormal light.Based on the hands-on experience in network management,it also defines the technical requirements on PON equipment capability and the mechanism and procedure to detect any ONU who emits light abnormally.

Key words: passive optical network, abnormal light emitting ONU, OLT, ONU
