The industry’s shift toward 448G signaling—driven by scale-up and scale-out AI cluster demands–and the evolving system architectures, standardization efforts and timing strategies required to meet deployment goals.
As Artificial Intelligence (AI) and Machine Learning (ML) workloads continue to reshape data center infrastructure, the need for higher bandwidth and lower latency has accelerated the need for a next-generation Ethernet. This white paper examines the industry’s shift toward 448G signaling—driven by scale-up and scale-out AI cluster demands—and outlines the evolving system architectures, standardization efforts (including IEEE P802.3 Ethernet for AI assessment and OIF CEI-448G), and timing strategies required to meet deployment goals. It also highlights considerations for electrical vs. optical connectivity, the role of co-packaged optics, and the foundational infrastructure needed to support 448G-ready AI networks.
