Optical Power Meter

Introduction
St805b pon Power Meter is specially designed for pon network construction and maintenance which can be connected between olt and ont. The voice, data, video signal (1310/1490/1550) online can be measured synchronously and optical power value (1310/1490/1550) can be displayed with this meter. It's a useful site test tool for the engineers of pon network and maintenance operators.
Main features and functions
