Product Demo

OTDR

The OTDR features flexible setup options, including launch and end fiber configurations. It supports customizable PASS/FAIL thresholds, visually distinguishes event qualifications, generates detailed PDF reports, and allows comparison of multiple SOR curves with advanced analysis methods like the four-point and LSA methods.

Event Map

RM7 features a powerful event map that supports macro bend fault analysis and identifies different types of macro bend events. It provides PASS/FAIL threshold judgment with flexible threshold customization, and distinguishes qualified and unqualified events with intuitive visual indicators. The system can auto-generate test reports that include curve traces, event lists, and other details.
