The Anritsu MW9076J is a field-deployable Optical Time Domain Reflectometer engineered for fiber characterization, fault detection, and maintenance across installation and operational lifecycles. It delivers fast trace acquisition with a 30 dB typical dynamic range, supporting both 0.85 µm and 1.3 µm wavelengths on graded-index fiber. The instrument acquires complete waveforms in 10 seconds during Full-Auto mode and performs real-time sweeps in 0.1 to 0.2 seconds or less, enabling rapid field diagnostics.
