Description
Overview
GAOTek optical fiber ranger live test adopts a 3.5 in (8.8 cm) high-definition touch screen, supports multi-touch and smooth operation. Internal integration of OTDR, event map, optical power, red light, flashlight and other functions in one, to meet various test needs in different occasions. Among them, the OTDR function adopts 1550 nm wavelength and built-in high-efficiency wavelength isolator. It can perform optical tests on 1490 nm and 1577 nm links. It supports up to about +10 dBm with optical test capability, and the maximum measurement range is 49.7 mi (80 km). This is used to measure the length, loss, connection quality and other parameters of the optical fiber. It can easily test the breakpoint, bend, and loss point of the optical fiber link. It is suitable for line maintenance and emergency repair testing by installation and maintenance personnel.
