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

Evidence

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

Context After

The SN6810 features one of these chips, while the SN6800 houses four, multiplexed together to create a 409.6T switch box. There will also be a non-CPO version with pluggable OSFP cages in the SN6600. The non-CPO version will be more common in our view.

② Atomic Claim

Package 上有 32 個 3.2T optical engines，將 electrical signals 轉為 optical links；每個 optical engine 都有 detachable fiber connector。
