The Anritsu MW9076C is a mini-OTDR (Optical Time Domain Reflectometer) engineered for field installation, maintenance, and fault location in single-mode optical fiber networks. Delivering dynamic range up to 45 dB typical with a Fresnel dead zone of 1.6 m and back-scattered dead zone of 8 m, the unIt has 5 cm resolution across 50,000 sampling points. Measurement cycle times span from 10 seconds in Full-Auto mode to 0.15 seconds in Real-time Sweep, enabling rapid network diagnostics and commissioning workflows.
