- Satisfaction guarantee
- Fast delivery
- Quality assurance
Description
The NK6200 Series Optical Time Domain Reflectometer (OTDR) is a new-generation 7-inch capacitive touch product that integrates 9 major functional modules including OTDR, optical power meter, and visual fault locator. It features an attractive and novel design with rich peripheral support. Utilizing excellent intelligent hardware and software design, it offers higher accuracy in short fiber testing and automatic testing. It also comes equipped with comprehensive Ethernet testing functions (Ping/PPOE/Cable Tracing, etc.) to diagnose Ethernet network faults, supports wireless control via mobile app, and allows easy access to test results.
The NK6200 Series is primarily used to measure parameters such as fiber optic cable length, loss, and splice quality. It is widely applied in engineering construction, line maintenance testing, emergency repair of fiber optic communication systems, as well as in the development, production, and measurement of fiber optic cables. Its main applications include urban trunk lines, backbone networks, and metropolitan area networks.
