Product Overview

The flagship of the NOVATEK OTDR range. A 7-inch 1024×600 display, up to 45 dB dynamic range and a 0.8 m event dead zone let it handle metro and trunk links, splitters up to 1/64 and live-PON troubleshooting. Data storage of 12 GB or more and one-click PDF test and diagnostic reports make it a complete field laboratory.

Data storage of 12 GB or more holds very large fibre estates without downloading in the field.

Online detection with APD active protection keeps live-PON work safe.
