Context Before

Evidence

While not part of the Rubin NVL72 rack, Spectrum-6 CPO enables even larger scale-out clusters with its doubled radix.

Context After

The design retains the same features as Spectrum-5, with 8 IO chiplets surrounding the main switch die. 102.4T switching bandwidth is achieved with 512x 200G SerDes. 32 3.2T optical engines on the package convert these electrical signals to optical links, each with a detachable fiber connector.

② Atomic Claim

Spectrum-6 CPO 雖不屬於 Rubin NVL72 rack，但藉由 doubled radix 可支援更大的 scale-out clusters。
