Context Before

While not part of the Rubin NVL72 rack, Spectrum-6 CPO enables even larger scale-out clusters with its doubled radix. The design retains the same features as Spectrum-5, with 8 IO chiplets surrounding the main switch die.

Evidence

102.4T switching bandwidth is achieved with 512x 200G SerDes.

Context After

32 3.2T optical engines on the package convert these electrical signals to optical links, each with a detachable fiber connector.

② Atomic Claim

102.4T switching bandwidth 由 512 條 200G SerDes 達成。
