NK6200 Series OTDR with 7-inch Touch Screen and Integrated Multi-Function Testing
- Satisfaction guarantee
- Fast delivery
- Quality assurance
Description
The NK6200 Series Optical Time Domain Reflectometer (OTDR) features a 7-inch capacitive touch screen and integrates 9 functional modules. With excellent intelligent hardware and software design, it delivers higher accuracy in short-fiber testing and automated measurements. It is equipped with rich Ethernet test capabilities (Ping, PPPoE, etc.) and supports APP control for remote operation.
The NK6200 Series is designed to measure optical fiber length, loss, and connection quality. It is widely used in engineering construction, link maintenance testing, and is primarily deployed in urban trunk lines, backbone networks, and metropolitan area networks.
