The Ethernet Alliance will stage a large-scale interoperability demonstration at ECOC 2025 in Copenhagen, highlighting how Ethernet is evolving to support AI, HPC, and next-generation networks. The live demo at booth C1419 will feature optical and copper connections from 100G to 800G, including Linear Pluggable Optics (LPO), showing Ethernet’s scalability, low latency, and efficiency in training and deploying complex AI models.
Participating member companies will showcase a broad range of technologies: Alphawave Semi will highlight its AlphaCHIP1600 I/O chiplet; Amphenol will focus on high-density connectors and cables; Cisco will bring its Silicon One switching platform with 400G/800G optics and coherent ZR/ZR+ interconnects; Formerica OptoElectronics, Huawei, Keysight, MultiLane, Synopsys, TE Connectivity, Teledyne LeCroy, and VeEX will demonstrate complementary components and test solutions. Collectively, the demo underscores Ethernet’s ability to interoperate across multiple vendors while supporting future-ready, AI-optimized networks.
Industry leaders emphasized the collaborative nature of the effort. “Ethernet is what brings our digital world together; it remains unrivaled at linking AI clusters, enabling fast data centers, and supporting these demanding networks,” said Peter Jones, chair, Ethernet Alliance and distinguished engineer at Cisco. Other executives from Alphawave Semi, Amphenol, Keysight, Synopsys, TE Connectivity, and more noted Ethernet’s central role in enabling faster insights, lowering latency, and meeting energy efficiency demands as AI scales.

“Ethernet is an ever evolving, interdependent ecosystem and interoperability is where its promise comes alive,” said Ethernet Alliance president and events and conferences committee chair, David J. Rodgers of EXFO. “This demo is a window into a future where Ethernet connects the planet’s most powerful compute engines with the same reliability, scalability, and efficiency that have defined it for decades. For AI, the promise is faster time-to-insight, more responsive applications, and a network foundation ready to evolve with the technology.”
🌐 Analysis: The Ethernet Alliance is positioning Ethernet as the backbone for AI and HPC networking, countering proprietary interconnect approaches like NVLink and UALink. With the rise of 800G and early 1.6T technologies, interoperability will be critical for hyperscale deployments. This multi-vendor showcase echoes similar efforts seen at OIF and OFC, but with a sharper focus on AI-driven data center architectures. It also demonstrates how member companies—spanning chipmakers, optics vendors, and test equipment suppliers—are aligning Ethernet to remain relevant in the face of custom AI interconnects.
