摘　　要：文章针对PON系统的基本保护要求,提出了光分路器(OBD)设计原则;采用最坏值法对PON系统最远的用户终端,进行ODN光通道衰减核算;同时,对ODN光缆线路进行分段衰减测试和全程衰减测试,测试结果满足FTTH系统工程规范。根据现场试验的研究和测试结果,规范光纤到户(FTTH)工程系统的规划、设计、施工、监理及竣工验收等工作。Firstly, on the basic protection requirements of PON system, explaining principles of designing OBD. Adopting worst value method on farthest ONU of PON system, calculating optical channel attenuation of ODN. At the same time, the attenuation of section and the whole attenuation are tested in fiber cable line of ODN, results of test fulfils engineering norm of FTTH system. The research results of field test could be the standardization and guideline of different kinds of work in the passive optical system, including planning, design, construction, supervision and acceptance of project completed.
