The need to transmit increasing amounts of data across high-speed optical networks is driving demand for components that leverage multiplexing technologies to increase bandwidth. Evaluating the characteristics and quality of these devices and components requires high-precision test instruments that are fast, accurate and easy to use.
Yokogawa Test&Measurement is helping to meet the evolving test needs of the industry with a comprehensive range of high-accuracy optical spectrum analyzers (OSAs) that will be on show at stand C2320 at ECOC 2025. Designed for exceptional performance, these instruments offer developers the tools they need to advance the latest optical designs and contribute to making digital communication more efficient and capable than ever before.
At ECOC 2025, visitors can explore:
The AQ6380 in particular is designed for ease and efficiency of use, ensuring the measurement scheme can be set up rapidly and data acquired easily. With wavelength coverage of 1200-1650 nm on the standard model and wavelength resolution from 5 picometres to 2 nm, the AQ6380 supports a wide range of applications from narrowband peak/notch measurements to wideband spectral measurements.
Together with these highlights, the comprehensive portfolio of Yokogawa OSAs covers wavelengths from ultraviolet light at 350 nm up to far infrared at 5.5 µm. Whatever the application and measurement requirement, Yokogawa offers a grating-based OSA that provides a configurable combination of high accuracy, high resolution, high sensitivity and wide dynamic range.

Visitors to ECOC 2025 can see the latest OSAs from Yokogawa Test&Measurement and other leading-edge solutions for accurate optical measurements in action at stand C2320.
