摘　　要：光宽带的规模建设带来了接入网光纤光缆的海量建设,大建设应用后重点在于光网运营维护管理,因而高效的光网检测手段及其相关的灵活应用方式非常重要。在分析ODN组网基础上,研究OTDR应用于ODN的测试能力,重点分析了OTDR测试中ODN关键事件的特征,同时根据ODN建设模式和OTDR检测缺点,针对性提出了相关应用方案。The construction scale of optical broadband network brings the massive construction of the access network optic fibers, and the key point is the operation, the maintenance and the management of the network after the large construction, thus it is very important to use highly efficient detection methods and related flexible application methods. Based on the analysis of ODN, the capability of OTDR applied in ODN was analyzed, and the characteristics of ODN key events in the OTDR test was focused, meanwhile according to OTDR detection shortcomings, relevant OTDR application schemes were suggested.
