Engineering record
Family-level values from the collected technical record. Confirm the selected SKU and required evidence in the quotation.
Technical detail
Review connector, construction, routing and handling details that apply to the selected family and exact SKU.
As B300 and GB300 GPU clusters continue to scale, growing rack-level interconnect density and connection counts are increasing deployment and cabling complexity, placing higher demands on interconnect reliability and deployment efficiency. Designed for such high-density GPU clusters, 1.6T ACC enables switch-to-switch interconnects within the same rack and between adjacent racks. Its integrated design reduces connection points, simplifies cabling, and eases deployment and maintenance. Built for high-speed, short-reach connectivity, it delivers reliable performance for large-scale GPU clusters.
