Frequently Asked Questions

?What is the main function of the NK4000 OTDR series?

The NK4000 series is an Optical Time Domain Reflectometer used to measure optical fiber length, transmission attenuation, connector loss, and to accurately locate faults and breaks along the fiber optic cable.

?What is the difference between standard models and live test models?

Standard models (NK4000S/NK4000D) are designed for dark fiber testing at 1310nm/1550nm. Live test models (NK4000F1/NK4000F2) feature active signal filtering to perform tests on active optical networks without interrupting service or damaging optical transceivers.

?How does the 2.5m event blind zone benefit my testing?

A short event blind zone of 2.5 meters allows the device to distinguish between closely spaced connections or splice points and accurately identify faults near the beginning of the fiber patch cable.

?Are the connectors interchangeable?

Yes, the device comes standard with a FC/UPC connector, and includes easily interchangeable interfaces to support SC and ST connector configurations.

?What data formats are supported for analysis report output?

The device supports the SOR Standard File Format, allowing you to easily view, save, and analyze traces using standard post-processing software on a computer.

?Is multitasking supported during testing?

Yes, the platform supports multitasking, allowing you to prepare configurations, manage files, or configure settings while testing is running in the background.
