Scale Optical Device Testing From R&D to Production
The Multi Application Test System (MATS) is an integrated platform for high-precision, high-throughput testing of optical devices, transceivers, and photonic components. Built with proven laboratory grade technology, it delivers stable, repeatable, and accurate measurements required in photonics R&D, new product introduction, and volume manufacturing.
Unlike other platforms, only Yokogawa offers a unified system with optical and SMU modules, hot-swappable reconfiguration, and proven long-term reliability in 24/7 high-volume production. For optical transceiver characterization, MATS is commonly paired with instruments such as OSAs, WLMs, BERTs, and high-speed oscilloscopes.

Static characterization of laser diode (LD) and photodiode modules
The AQ2300 streamlines the test by synchronizing source measure unit (SMU) and optical power meter (OPM) measurements during sweep measurements in a single test platform. enabling electrical and optical parameters to be synchronously acquired in a single platform. This built-in inter-channel synchronization enables efficient I-L characterization without additional external synchronization wiring. For more comprehensive optical characterization, the measurement system can be integrated with the AQ6151B Optical Wavelength Meter and AQ6361/AQ6370E Optical Spectrum Analyzer to evaluate wavelength and spectrum alongside electrical and optical power characteristics.

One of the challenges for engineers involved with the development or maintenance of complex electromechanical systems is to link the behavior in one part of a system to control signals in another. In particular, engineers often need to understand causality: the relationship between an event (the cause) and a second event (the effect) to obtain an insight into an electromechanical system’s overall behaviour and to plan corrective actions accordingly.

How-tos
This video demonstrates side mode suppression ratio (SMSR) analysis using an AQ6370E OSA and explains how to adjust the signal span to capture side modes and execute SMSR analysis to detect and locate the closest peaks from a 1310 nanometer laser via a connected light source module. SMSR analysis allows engineers to quickly identify and quantify the differences between the main peak and any side peaks in terms of nanometers and power which helps ensure the quality and accuracy of a laser's output. Manufacturers want to see a single, clean peak in a laser's output without side modes or additional peaks, to indicate a laser is performing as expected.
