Keysight Technologies Unveils Game-Changing UALink 1.0 Compliance Test Solution

On October 9, 2025, Keysight Technologies Inc. (NYSE: KEYS) announced the launch of its UALink 1.0 (Ultra Accelerator Link) transmitter compliance test solution, a pivotal development aimed at enhancing high-speed validation for advanced computing and AI interconnect systems. This innovative tool is specifically designed for UALink devices, automating crucial electrical measurements to ensure both signal integrity and adherence to standards at an impressive 200 Gb/s link speeds.

The UALink 1.0 technology was first introduced by the UALink Consortium in 2024, establishing an open standard that caters to the increasing demands of data centers. As the landscape of data-driven applications—such as AI, cloud services, and smart devices—continues to evolve, traditional interconnect technologies like PCIe® and Ethernet are falling short in meeting the necessary performance benchmarks. The UALink 1.0 standard represents a significant step forward in interconnect technology for AI data center infrastructure, facilitating rapid deployment of scalable silicon for AI communications.

Keysight's UALink 1.0 test solution revolutionizes the process of transmitter compliance testing by introducing automated procedures that significantly reduce the time required for testing. Tasks that previously took hours of manual labor can now be accomplished within minutes using the Keysight UXR Real-Time Oscilloscope combined with the new UALink 1.0 transmitter application.

Dr. Joachim Peerlings, Vice President of Network and Data Center Solutions at Keysight Technologies, emphasized the transformative impact of UALink on AI infrastructure. He stated, “The introduction of UALink marks a transformative leap in AI infrastructure and directly addresses the lack of an open, industry-standard, high-bandwidth low-latency interconnect for scaling AI accelerators within data centers. By providing tools for validating UALink transmitters, Keysight is helping the industry accelerate the introduction of products based on the open UALink standard.”

Keysight will showcase the UALink compliance test solution for the first time at the 2025 OCP Global Summit, scheduled for October 13-16 in San Jose, California, at booth #C1. This event will serve as a platform for industry professionals to witness firsthand the capabilities of this groundbreaking technology.

Additionally, Keysight is set to unveil an electrical 212 G receiver conformance test application (M8091DJCA) at the summit. This application supports cable and backplane interfaces, fundamental components of the UALink 200 Gb/s 1.0 standard and a key enabler for AI scale-up networking. The solution integrates a Keysight M8050A 120 Gbd High-Performance BERT, a Keysight Infiniium UXR Real-Time Oscilloscope, and the M8091DJCA compliance application to provide automated testing and advanced measurement coverage.

With the launch of the UALink 1.0 transmitter compliance test solution, Keysight Technologies is poised to significantly enhance data center interconnect testing, reinforcing its commitment to driving innovation within the industry. As the demand for advanced computing and AI technologies rises, Keysight's latest offering will play a crucial role in ensuring that the infrastructure supporting these technologies can meet the escalating performance standards.
