Description
Overview
GAOTek mini handheld measure test OTDRs feature a 3.5 in (88.9 mm) color screen, double operation of keys and touch. They have a simple interface, highly optimized parameter configuration, and a maximum 32 dB dynamic range. They integrate Visual Fault Location and adopt intelligent power-saving technology, providing 10 hours of super long standby to ensure efficient field test work. The mini OTDRs are primarily used to measure the length, loss, and connection quality of optical fiber and cable. They are widely used in engineering construction, link maintenance tests, emergency repairs, and development and production measurements of optical fiber communication systems. They are mainly utilized in LANs, access networks, and FTTH setups.
