The NK2800 mini optical time domain reflectometer is compact and easy to carry; it adopts a 3.5-inch high-definition touch screen, supports multi-touch and smooth operation. Internal integration of OTDR, optical power, red light, flashlight and other functions in one, to meet various test needs in different occasions. Among them, the OTDR function adopts 1550nm wavelength and built-in high-efficiency wavelength isolator. It can perform optical test on 1490nm and 1577nm links. The maximum measurement range is 80km.
