AI Interconnect at Scale: Where Copper Ends and Optical Begins

<p>The scaling of AI infrastructure from single racks to multi-rack and campus-scale clusters is forcing system architects to rethink how data center interconnects are designed. As deployments grow to support tens of thousands of accelerators, scale-up and scale-out interconnect choices directly impact system efficiency. Bandwidth remains part of the equation, but power, reach, density, and [&#8230;]</p> <p>The post <a href="https://www.hpcwire.com/2026/09/15/ai-interconnect-at-scale-where-copper-ends-and-optical-begins/">AI Interconnect at Scale: Where Copper Ends and Optical Begins</a> appeared first on <a href="https://www.hpcwire.com">HPCwire</a>.</p>
