AI racks are becoming some of the most complex systems in modern infrastructure, combining high-density compute, advanced cooling, and increasingly intricate interconnect architectures.

This whitepaper from AFL explores how power delivery, fabric design, and fiber connectivity are converging inside the rack, creating new engineering challenges while reshaping how infrastructure is designed and deployed.

Drawing on historical parallels and current market shifts, it highlights how today’s complexity may represent a transitional phase rather than a fixed end state.

With optical innovation accelerating and new architectures emerging, the paper provides a forward-looking perspective on how AI infrastructure can evolve toward more scalable, efficient, and simplified designs.
