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.

Expert OTDR:Professional measurement,curve/list/map are displayed simultaneously

Auto OTDR: no complex settings,one key test

OPM supports CW/270/330/1k/2kHz frequency identification

VFL and LS can run in the background, multi task can be operated simultaneously

LS supports CW/ modulation mode output with adjustable output power

RJ45 cable tracker of digital radar,stronger anti-jamming ability

Auto OTDR, expert OTDR, event map, OPM, LS, VFL, RJ45 cable tracking, RJ45 cable sequence,RJ45 cable length, end face detection, flashlight optical loss test

RJ45 cable sequence/cable length test, up to 300m

One click screen capture, easy to save the interface
