摘要

网络管理和维护一直是保证网络正常运行、提高客户感知的重要手段。PON（无源光网络）作为宽带接入的主流技术正被各大运营商广泛采用

如何对PON进行有效的管理维护成为各方关注的重点

而ODN（光分配网）的管理和维护也就成为重中之重。文章从ODN存在的故障及运维中面临的问题出发

介绍现有ODN的总体情况

并讨论现有的各种故障诊断技术

分析了各技术方案的优缺点

以及适用的组网模式、定位效果等。

Abstract

Network management and maintenance has always been an important means for ensuring normal network operation and improving customer perception.As a principal technology for broadband access

Passive Optical Network（PON） is widely adopted by major operators.Therefore

the effective management and maintenance of PON become a major focus of attention and that of Optical Distribution Networks（ODN） is of first priority.Starting with the faults in ODN and the problems in its operation and maintenance

this paper introduces the general situation of the existing ODN

discusses the existing fault diagnosis techniques and analyzes the advantages and disadvantages of various technical schemes and the suitable networking modes and location effects.
