NK3200 Mini PRO Series Optical Time Domain Reflectometer (OTDR)

Description

The NK3200 Mini PRO Series Optical Time Domain Reflectometer (OTDR) features a 3.5-inch color display with a simple UI interface. It integrates 8 major functions, including OTDR, stable light source, optical power meter, red light source (visual fault locator), wire sequence testing, cable length testing, cable tracing, and illumination. With optimized parameter configuration, it maximizes the simplification of testing operations. The compact body is easy to carry; equipped with intelligent power-saving management, it offers up to 12 hours of ultra-long measurement time, efficiently ensuring field testing and maintenance operations.

The NK3200 Series is primarily used to measure parameters such as length, loss, and splice quality of various optical fibers and cables. It remains usable even when there are communication optical signals in the line, with a maximum live fiber test signal power of -5 dBm. It can be widely used in engineering construction, line maintenance testing, emergency repair, as well as research, development, and production measurement of optical fiber cables in fiber optic communication systems.
