Description
Overview
GAOTek transmission fiber attenuation value testing is one intelligent and efficient instrument that combines in one set the functions of both a digital optical phone and a stabilized light source. It is widely used in operations of installation, optical testing, maintenance and fiber attenuation value testing in data network, CATV and telecommunication network. It can carry out full duplex communication with high quality connection and not be affected by distance.
Features
