Optical Spectrum Analyzer Tackles Production Testing

March 20, 2025
Yokogawa's OSA serves manufacturers of photonic devices and modules for optical communications.

What you'll learn:

  • How the rise in AI-dedicated data centers are increasing the demand for optical modules and devices.
  • How testing optical devices, optical modules, and other optical components require faster, smaller, and higher-performance OSAs.
  • How the AQ6361 optical spectrum analyzer addresses meets these production needs.

 

The widespread adoption of machine learning has had a dramatic impact on society, leading to a rapid increase in the creation of AI-dedicated data centers that need to process large amounts of data at high speeds. This, in turn, is driving a surge in the demand for optical modules and devices for high-speed data transfer. Those producing optical devices, optical modules, and other optical components demand faster, smaller, and higher-performance test solutions to meet this escalating demand. 

Addressing this issue, Yokogawa Test & Measurement recently released the AQ6361 optical spectrum analyzer (OSA). It's designed predominantly to perform production testing of datacom and telecom components like laser diodes, optical transceivers, and optical amplifiers.

APEC 2025

Here's our ongoing coverage of the latest power technologies from APEC 2025.

The compact AQ6361 offers up to 20X the measurement speed of legacy devices, meeting production needs with fast measurements and excellent optical performance. It also satisfies demands for a solution that doesn't compromise on quality and reliability, significantly reducing the production test time for optical devices.

Approximately half the size of legacy solutions, the AQ6361 brandishes a space-saving design that's also suitable for integration into laser diode chip testers and other evaluation systems. It offers a wavelength resolution of 0.03 nm and a wavelength range of 1,200 to 1,700 nm, providing high dynamic range measurements with 73 dB of stray light suppression, making it adaptable for various optical module testing.
