摘要
文章介绍了一种无源光网络(PON)系统中测试用的光功率计,该功率计通过特殊设计的光路和电路结构来实现PON系统中对信号光功率测试的特殊要求,即要满足线路上3种光信号波长的同时测试、在线测试和1 310 nm信号的突发测试功能,从而大大方便PON系统的安装、管理和维护。
This paper introduces an optical power meter for PON system measurement. With specially designed optical and electrical circuit structures, The power meter satisfies the specific requirements for optical signal power measurements in PON systems i.e. simultaneous and online measurements of three optical signal wavelengths in the line and the burst measurement of 1 310 nm optical signal, thus greatly facilitating the installation, management and maintenance of the system.
