Mini OTDR Active Fiber Live Tester 1550nm (±20nm) 20dB Dynamic Range 100m–80km Touch Screen OPM Event Map

Compact Mini OTDR designed for active/live optical fiber testing. The unit operates at 1550nm (±20nm) and provides a 20dB dynamic range, enabling reliable measurements across fiber lengths from 100m to 80km. A sturdy connector ensures stable, low-interruption coupling to the fiber under test for consistent results. Multiple measurement modes — real-time, average, and automatic — let you choose the best testing method for each situation. The instrument includes input light detection and generates OPM/Event Map readouts to help locate and characterize faults quickly. An intuitive touch screen interface streamlines operation and review of accurate measurement data, making field testing faster and more efficient.
