Yokogawa AQ7420 High-Resolution Reflectometer

Precise quality control of optical connectors and modules

The Yokogawa AQ7420 reflectometer is an advanced tool designed for accurate quality control of fiber optic connectors and optical modules. Thanks to its exceptionally high spatial resolution, the instrument precisely detects the location and measures the magnitude of reflections inside the analyzed components.

Detect hidden defects, prevent failures

The AQ7420 is indispensable for identifying microcracks and other subtle defects that often remain undetected during standard attenuation measurements. Detecting these hidden defects at an early stage is crucial for ensuring the reliability of optical systems, especially those operating in demanding conditions (exposed to movement, vibration, thermal cycling). This helps avoid unexpected and costly failures in critical infrastructures.

Versatility and measurement reliability

Combined with the optional Sensor Head AQ740023, the AQ7420 reflectometer gains the ability to simultaneously measure insertion loss, making it an ideal, multifunctional instrument for comprehensive inspection of connectors and modules. High sensitivity and an exceptionally low phantom noise level (-100 dB) guarantee reliable results and eliminate the risk of false detections (“ghost” effects).

Key features:– Measurement range: 100 mm (approx. 4 inches) – ideal for analyzing connectors and module interiors.- High spatial resolution: 40 µm – enables precise localization of reflections.- Low phantom noise level: -100 dB – ensures reliable measurements without false signals.- Wide reflection measurement range: from -14.7 dB to -100 dB (depending on the mode).- Simultaneous measurement of multiple reflections and insertion loss (optional Sensor Head AQ740023 required).- Fast measurement: approx. 6 seconds.

Applications:

Detection of microcracks in optical connectors used in:– Datacenters- Submarine fiber optic systems- Mobile phone towers (FTTA – Fiber To The Antenna)- Satellite systems

Precise localization and intensity measurement of internal reflections in optical devices such as:– Silicon Photonics components- TOSA/ROSA transceiver modules

The Yokogawa AQ7420 is an essential tool for optical component manufacturers, system integrators, and quality control teams that require the highest precision and reliability in fiber optic connection inspection.
