Context Before

For Rubin Ultra NVL144 Kyber, there will be no CPO used for scale up, despite rumors from other analysts suggesting scale-up CPO introduction for Kyber. However, optics for NVLink are coming and will be progressively phased in.

Evidence

Scale-up CPO will first be used for the Rubin Ultra NVL576 system to connect between 8 Oberon form factor racks, forming a two-layer all-to-all network.

Context After

A copper backplane will still be used for scale-up networking within the racks however. This is still for low volume / testing purposes.

② Atomic Claim

scale-up CPO 會先用在 Rubin Ultra NVL576，連接 8 個 Oberon form-factor rack，形成 two-layer all-to-all network。
