NK4000 series OTDR adopts 4.3-inch capacitive touch screen. It integrates 12 functions, such as auto OTDR, expert OTDR, event map, OPM, RJ45 cable tracker, and “computer level” file management to meet various test requirements in different occasions. OTDR has a maximum dynamic range of 26dB, 8G memory, and can store more than 200,000 curves; it is equipped with 4000mAh highdensity polymer lithium battery, intelligent power saving management, measuring time of more than 8 hours, and supporting power supply and charging of the power bank.
NK4000 series are used to measure the length, loss, connection quality and other parameters of optical fiber. It is widely used in FTTX, secondary backbone network engineering construction, maintenance and emergency repair test, and production measurement of optical fiber and cable.
