NOVKER NK6800-D35 SINGLE MODE OTDR 1310/1550nm 35/33dB MULTIFUNCTION OPTICAL FIBER TESTER OT072

The NOVKER NK6800-D35 MAX-OTDR is a professional multifunction Optical Time Domain Reflectometer designed for testing, troubleshooting, commissioning and maintaining single-mode fibre-optic networks.

The D35 version operates at 1310nm and 1550nm wavelengths, with a maximum dynamic range of 35dB at 1310nm and 33dB at 1550nm. It is suitable for testing longer fibre links and identifying fibre events such as connectors, splices, bends, breaks and end points.

Besides standard OTDR testing, the NK6800 platform integrates several useful fibre-testing functions, including optical power measurement, visual fault locating, optical light source testing, event-map analysis and fibre-end inspection. NOVKER categorises the NK6800 as a MAX-OTDR for wide-area network applications.
