AFL：2026年在16K加速器上构建Al训练集群白皮书（英文版）

AI cluster deployments are approaching scales where physical infrastructure becomes a primary design constraint. Fiber count, building layout, breakout strategy, optical reach, and power density all influence deployment feasibility, facility design, operational efficiency, and future expansion. A scalable physical network architecture must accommodate growth without introducing unnecessary complexity into the cabling plant. Growth involves more than increasing fiber count. Larger deployments
