Why Power, Not Compute, Limits AI Scaling

AI data centers are scaling at an unprecedented pace, but the constraints shaping that growth are changing. While GPUs and accelerators continue to advance rapidly, <strong>power delivery, power efficiency, and heat dissipation increasingly define how far and how fast AI clusters can scale</strong>.

Optical Circuit Switches in AI Hyperscale Data Centers – The MEMS Advantage

Optical circuit switching (OCS) is drawing intense interest when it comes to improving data center networking (DCN) in AI hyperscale environments, where efficient workload processing hinges upon massive parallelism, real-time data movement, and ultra-low latency networking. OCS was a leading topic of conversation at the recent ECOC Conference and Exhibition where we announced our new OCS R64 platform, the second member of the OCS family after the <a href="https://www.lumentum.com/en/media-room/news-releases/lumentum-optical-circuit-switch-improve-next-generation-ai-data-center">R300</a> which we introduced earlier this year at OFC in San Francisco.
