Context Before

In multi-plane network architectures using the SN6600 switch instead of the CPO switch, each GPU fans out to multiple switch boxes using fiber shuffles. This requires customers to deploy shuffle boxes, patch panels and unwieldy octopus cables outside the switch box that introduce complexity in installation and maintenance.

Evidence

Some of Nvidia’s CPO SKUs—such as the SN6800 and Q3450—contain such a fiber shuffle within the switch box, with each optical engine fanning out to different logical ports.

Context After

They therefore deliver higher aggregate bandwidth—409.6T and 115.2T respectively—than is possible with a switch box based on a single Switch ASIC.

② Atomic Claim

Nvidia 的部分 CPO SKUs，例如 SN6800 與 Q3450，把 fiber shuffle 整合在 switch box 內，讓每個 optical engine fan out 到不同 logical ports。
