摘要
介绍了无源光网络的工程设计特点 ,分析了ITU TG 982推荐采用的高斯统计法的应用限制 ,并介绍了一种新的无源光网络设计预算的简便方法———PON均值查图法 ,该方法的特点和A、B图及查图使用方法。最后试用PON均值查图法 ,对一个包含有 1∶3非均匀分光器的 4级连 1/ 8无源分配网络进行了工程设计预算。
The paper describes engineering design characteristics of passive optical networks(PON),and analyses applying restrictions of Gaussian statistical approach recommended by ITU T G982,the presents a new simplified method for PON engineering budget designing:PON average chart techniques.The paper describes characteristics of this method,chart A & chart B,and how to use these techniques.Finally,applying with PON average chart techniques,the paper makes budget designing example of an 1 to 8 PON distribution system,which has 4 optical splitters cascaded,and includes some 1∶3 splitters.
