Ethernet Alliance hosts multi-vendor interoperability demo at ECOC
In booth #2173 at the European Conference on Optical Communication (ECOC 2026) in Malaga, Spain (21–23 September), the Ethernet Alliance is hosting a live multi-vendor interoperability demonstration 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.
“AI has a seemingly insatiable appetite for bandwidth, and Ethernet is evolving at an incredible pace to help keep up,” says the Ethernet Alliance’s president & chair David J. Rodgers. “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 also explores 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 Corp; Cisco Systems Inc; HPE; Huawei Technologies Co Ltd; Hyper Photonix Ltd; Keysight Technologies Inc; MultiLane Test Products; Synopsys Inc; TE Connectivity plc; Teledyne LeCroy Inc; VeEX Inc; and Wilder Technologies LLC.
The Ethernet Alliance is also taking part in the ECOC 2026 Market Focus panel ‘The Ethernet Evolution of AI‘ on 23 September (12:00–12:55pm CEST). The session explores 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, (7–8 October) in Mountain View, CA, USA. 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.
