Description
Overview
GAOTek Visual Fault Locator is a handheld and intelligent measuring instrument. It adopts a 3.5 in (8.89 cm) color screen, double operation of keys and touch. It has a simple interface, highly optimized parameter configuration and max 32 dB dynamic range. It integrates Visual Fault Location and adopts intelligent power saving tube 10 hrs of super long standby to ensure the field test works efficiently. is mainly used to measure the length, loss and connection quality of optical fiber and cable. It is widely used in engineering construction, link maintenance tests, emergency repair, development and production measurement of optical fiber communication systems. It is mainly used in LAN, access network and FTTH.
