The Anritsu MW9076B is a compact optical time domain reflectometer engineered for field fiber diagnostics and verification. It delivers rapid trace acquisition with integrated display and automated measurement modes, enabling technicians to execute comprehensive fiber characterization from a single keypress. The instrument combines OTDR, chromatic dispersion analysis, Fresnel reflection measurement, and light source functions in a single platform, with real-time sweep capability of 0.15 seconds and waveform/connection loss display within 10 seconds.
