Keysight Expands 1.6T Ethernet Validation Across Edge Routing, High-Density Switching, and AI Workload Emulation

SANTA ROSA, Calif.--(BUSINESS WIRE)--Oct 13, 2026--

Keysight Technologies, Inc. (NYSE: KEYS) today announced two new 1.6T Ethernet test platforms, Switch and Edge Router Tester (SERT) 1600GE and AresONE Plus 1600GE, designed to help customers validate next-generation AI data center and hyperscale networking infrastructure. AresONE Plus 1600GE sets a new benchmark by delivering eight 1.6T Ethernet ports in a single 2U appliance while providing stateful, realistic AI workload generation with mix-of-experts emulation.

SERT 1600GE targets data center switch fabric and edge router validation, while AresONE Plus 1600GE adds AI workload emulation and high-density switch fabric testing. The combined platforms provide a consistent test foundation for device qualification, routing, and AI fabric validation. They also enable performance, interoperability, and control-plane evaluation as networks scale.

Key capabilities include:

NVIDIA Spectrum-6 Ethernet Switch is setting the foundation for next-generation AI Ethernet fabrics with unprecedented bandwidth, scale, and AI-optimized networking. Through collaboration with NVIDIA, Keysight AresONE Plus 1600GE provides the high-performance validation platform needed to stress these capabilities with 1.6T/800GE traffic throughput, 224G SerDes, routing-scale validation, and realistic AI workload emulation, enabling rigorous performance and congestion testing before deployment.

Gilad Shainer, Senior Vice President of Networking, NVIDIA, said: “AI factories require an Ethernet fabric designed for accelerated computing, and NVIDIA Spectrum-X provides the performance, predictability and control needed to keep large-scale AI workloads running efficiently. Keysight’s validation capabilities help engineering teams emulate realistic AI traffic and test Spectrum-X-based fabrics before deployment, reducing time to market.”

Ram Periakaruppan, Vice President and General Manager, Network Test & Security Solutions, Keysight, said: “The AI era breaks the rules for hyperscale infrastructure. We have moved beyond fault-tolerant commodity scaling to highly synchronized, specialized AI clusters where every packet, link, node, and nanosecond counts. As engineering teams and operators race to upgrade AI infrastructure to 1.6T Ethernet, they need to emulate the broader AI system throughout the development process—from early design and device qualification to system-level validation and AI rack deployment. These new platforms give our customers the flexibility to test at scale while using the same test foundation across the entire design-to-deployment continuum.”

Keysight is showcasing the new platforms at Open Compute Project (OCP) Global Summit booth #C83 in San Jose Convention Center, October 12-15.

WASHINGTON (AP) — The Supreme Court agreed Tuesday to hear arguments in a watchdog’s lawsuit seeking public records about trillionaire Elon Musk’s Department of Government Efficiency.

The high court is intervening for a second time in Citizens for Responsibility and Ethics in Washington’s case, which seeks access to DOGE records from its operations in the early days of President Donald Trump’s second term. The Trump administration asked the court to hear the case.

Last year, the high court reined in a district court’s order for the government to produce DOGE-related records to CREW. The high court’s conservative majority concluded in June 2025 that U.S. District Judge Christopher Cooper ruled too broadly in ordering documents to be turned over to the group.

CREW claims DOGE is a federal agency and therefore is subject to the Freedom of Information Act.

The Trump administration argues that DOGE is exempt from FOIA’s requirements as a presidential advisory body.

Cooper ruled in CREW’s favor and ordered expedited processing of the group’s records request. An appeals court panel also sided with CREW.

The Trump administration claims the panel ignored the Supreme Court’s direction to consider separation-of-powers concerns and intruded on the “autonomy and confidentiality” of presidential advisers.

“Subjecting advisory bodies to intrusive discovery triggers the very concerns that Congress sought to avoid by excluding presidential advisory bodies from FOIA’s reach,” Justice Department attorneys wrote.

The administration also says the appeals court impermissibly authorized the plaintiffs to take a sworn deposition of DOGE acting administrator Amy Gleason.

CREW says the appeals court fully complied with the Supreme Court’s previous order. The group also asserts that the public has a right to know how DOGE helped the administration carry out a sweeping overhaul of government operations in 2025.

“Undisputed facts in the public record — including the President’s statements — confirmed that (DOGE) was wielding enormous independent authority across the federal government,” its attorneys wrote.

In a statement Tuesday, CREW attorney Nikhel Sus said the lower courts have uniformly ruled that it is entitled to records that could help the court determine whether DOGE wields the type of authority that would make it subject to the Freedom of Information Act.

“We will continue to pursue transparency for the American people, who deserve to know the details of the Trump Administration’s efforts to unilaterally remake the federal government,” Sus said in the statement.
