摘　　要：目前基于PON(无源光网络)技术的FTTx光接入网正在快速发展,光接入网的维护和管理面临着巨大的挑战,对高效的网络维护和管理手段尤其是业务验收及故障诊断的方法、工具的需要显得尤为迫切。文章从FTTx光接入网维护管理中需要解决的关键问题出发,简要分析了FTTx光接入网综合测试系统功能需求,并在此基础上提出了适合基于PON技术的FTTx光接入网测试架构方案。At present, PON-based FTTx optical access networks are growing rapidly. However, they are facing enormous chal- lenges in terms of maintenance and management and urgently require efficient network maintenance and management tools, es- pecially the methods for service acceptance and fault diagnosis. Starting from the key issues to be tackled in network mainte- nance and management, this paper briefly analyzes the functional requirements for the integrated test systems for optical access networks and, on this basis, presents the test architecture scheme appropriate for the PON technology-based FTTx optical ac- cess networks.
