The Anritsu MW9076 Mini OTDR is a compact, ruggedized optical time domain reflectometer engineered for field service and FTTx deployment. Measurement speed defines its operational advantage: Full-Auto mode completes traces in 10 seconds, while real-time sweep operates at 0.15 seconds—3 to 5 times faster than the MW9070B predecessor. The 5 cm resolution and up to 50,000 sampling points enable precise fault localization and event analysis.
