AQ740051 Expander Unit

Extend High-Resolution Optical Inspection

The AQ740051 Expander Unit extends the measurable distance range of the AQ7421 High-Resolution Reflectometer, enabling high-resolution inspection of optical paths up to 8 meters.

By expanding the measurable distance range, the AQ740051 supports accurate fault location and reflection analysis for short fiber assemblies and integrated photonic devices that exceed 1 meter in length but remain unsuitable for long-haul OTDR testing. It helps engineers identify connection points, internal reflections, and potential defects with high spatial resolution.
