  • Product Overview:

    Hand-held Optical Time Domain Reflectometer of NK2000 Series is a newly hand-held and intelligent communication measuring device in accordance with the test of Optical fiber and Communication System. The product is used to measure the parameters like optical fibers, length of the optical fiber, loss, following quality and the like. It can quickly and accurately position the case point and fault point of the optical fiber link. It can be widely used in the engineering construction, route maintenance and urgent repair of the Optical fiber and Communication System. It can also be used in optical fiber and optical cable development as well as production measurement. The product can effectively do help to the installation and construction of the optical fiber network, the following speedy and effective maintenance and the troubleshooting test.

    NK2000 is sturdy and durable with a novel and attractive appearance. The most succinct operation interface with a simple and intuitive style is specially designed for the domestic users. The dual operation mode of press key and touch screen effectively simplifies the application of the users. You can obtain the test result by the one-click analysis and the events will appear on the main interface in a list form with the information of event number, type, location (distance), loss, reflex, gradient of the events (attenuation) and total loss. Intelligent power management mode is employed to the machine. The working duration of the machine can be more than 10 hours with the high-capacity lithium battery.

    The most succinct and direct operation mode in the industry

    OTDR of NK2000 Serious is equipped with the most succinct operation interface, which is specially designed for the users. With a simple and intuitive style, there are only 6 operation menus on the optimized interface. The operation is so simple that it is easy to acquire it without professional training. The unique dual operation mode of press key and touch screen among the similar products in the industry effectively simplifies the application of the users.

    The independent and convenient one-click analysis function

    OTDR of NK2000 Serious is equipped with shortcut key of trace analysis, which can quickly and accurately find the event point or fault point and its position information of the trace tested. Then it will list all the information in the circuits, which do great help to the maintainers, improving the testing efficiency as well as ignoring the cumbersome background.

    High test index

    The tiny test dead zone and large dynamic range of NK2000 OTDR can meet both the testing of optical fiber wire jumper and the long-distance testing field . It is of highest cost performance!

    Automatic circuit is equipped with light alarm function

    When OTDR is testing optical fiber link, the result will be inaccurate if there is communication optical signal in the optical fiber. Communication optical signal may even damage the optical receiver of the machine. NK2000 OTDR can automatically monitor the communication optical signal in the optical fiber. Once the optical signal is detected, the connector will give an alarm, which provides the machine with a fastest and timeliest protection.

    High-power visible red light fault location function

    NK2000 OTDR built-in high-power visible red light fault location function can find the short distance optical fiber link breakpoint or the position of a big loss point conveniently and directly. Combined with OTDR function, it can enable a seamless monitoring of the chain and test, so that the maintainer can take measures in time and save time.

    Universal light interface design which is easy to be replaced

    The universal light interface equipped to NK2000 OTDR is easy to be replaced and cleaned. It can enable tests for many kinds of interfaces such as FC, SC and ST.

    High-efficient and flexible simulation software

    The simulation software can analyze, edit and derive the data stored by instruments, and it can generate the complete and professional OTDR report in a convenient and fast way.
