BEAVERTON, OR, Sept. 09, 2026 (GLOBE NEWSWIRE) — The Ethernet Alliance, a global consortium dedicated to the continued success and advancement of Ethernet technologies, today announced details of its live multi-vendor interoperability demonstration at ECOC 2026 booth #2173. The event will take place September 21–23 in Malaga, Spain.
The demo comes at a pivotal moment for high-speed Ethernet, as bandwidth and performance requirements continue to climb and the 1.6 Terabit Ethernet ecosystem gains momentum. IEEE P802.3dj, which includes new specifications for 1.6Tb/s Ethernet, is also advancing through the standards process. At ECOC 2026, attendees will get a real-world look at the technologies enabling 1.6T.
“AI has a seemingly insatiable appetite for bandwidth, and Ethernet is evolving at an incredible pace to help keep up,” said David J. Rodgers, president and chair, Ethernet Alliance. “Our ECOC 2026 demo showcases 1.6T solutions alongside the broader high-speed Ethernet ecosystem, showing how interoperability is helping to turn innovation into real-world connectivity.”
Spanning 400G, 800G, and 1.6T Ethernet, the exhibit features switches, test platforms, modules, cables, and a wide array of interconnects. Planned demonstrations include 1.6T OSFP connectivity and 1.6T operation using 224G SerDes technology and link training. An 800G AI lossless link demonstration will also explore link negotiation and lossless Ethernet mechanisms, including Link Layer Retry (LLR) and Credit-Based Flow Control (CBFC).
Ethernet Alliance members contributing to its ECOC 2026 interoperability demonstration include Amphenol Corporation (NYSE: APH); Cisco Systems Inc. (NASDAQ: CSCO); HPE (NYSE: HPE); Huawei Technologies Co., Ltd.; Hyper Photonix Ltd.; Keysight Technologies Inc. (NYSE: KEYS); MultiLane Test Products; Synopsys Inc.; TE Connectivity plc (NYSE: TEL); Teledyne LeCroy Inc. (NYSE: TDY); VeEX Inc.; and Wilder Technologies, LLC.
The Ethernet Alliance will also take part in the ECOC 2026 Market Focus panel, The Ethernet Evolution of AI, on Wednesday, September 23, from 12:00–12:55 p.m. CEST. The session will explore what comes next as AI networks move beyond today’s 200Gb/s-per-lane technologies and look toward speeds beyond 1.6T, including industry efforts toward 400Gb/s electrical and optical signaling.
ECOC 2026 also comes just two weeks before the organization’s 2026 Technology Exploration Forum (TEF), The AI Future: Ethernet, taking place October 7–8, 2026, in Mountain View, Calif. While ECOC highlights high-speed Ethernet in action, TEF will take the conversation further, exploring the architectures, standards, and technologies needed to support the next generation of AI infrastructure.
