NK3200 Mini Pro Series Optical Time Domain Reflectometer adopts 3.5 inch color display screen. The UI operation interface is simple and easy to operate. It integrates OTDR, Stable Light Source, Optical Power Meter, Visual Fault Location, Cable Sequence, Cable Length, Cable Tracker and Flashlight. It adopts intelligent power saving management, 12 hours of super long measurement time to ensure the field test and maintenance work efficiently. NK3200 series are used to measure the length, loss, connection quality and other parameters of all kinds of optical fiber and cable. When there is optical signal in the line, it can still be used. The maximum test power with light is -5dBm. It can be widely used in engineering construction, link maintenance test and emergency repair of communication system of optical fiber communication system.
