Analysis: The Backbone of AI - Navigating the Current 800G Market and the Road to Next-Generation Interconnects

Market analysis of the datacenter includes the network transition from 400G to the current 800G, deep-dive forecasts, market evolution toward Co-Packaged Optics (CPO), and the resulting impacts on the semiconductor supply chain.

The surge in Generative AI (GenAI) is catalyzing a generational shift in datacenter architecture. As LLM clusters scale to tens of thousands of GPUs, the interconnect has become the primary bottleneck. As AI networks transition beyond current 800G standards, the 2026-2028 window stands out as a crucial architectural turning point for companies seeking long-term market leadership. This report provides a comprehensive market analysis of the datacenter network transition from 400G to the current 800G "sweet spot," followed by projected uptake of 1.6T and 3.2T technologies. It includes deep-dive forecasts, market evolution toward Co-Packaged Optics (CPO) (the integration of chip-scale optical engines directly onto the silicon substrate), and the resulting impacts on the semiconductor supply chain.
