Context Before

Evidence

Single plane network with 1.6T OSFP cages at the NIC.

Context After

For Meta, we think the VR NVL72 deployments will comprise only of non-scheduled fabric (NSF) clusters built using Tomahawk 6-based Minipack-4 OCP Rack 102.4T switches in each datacenter. While Meta will be using optics to connect all the switches within its cluster, it will use 1.6T AECs for NIC-to-TOR connections once 1.6T AECs become broadly available in the market. We expect the 1.6T AEC ramp to happen in the second half of calendar year 2026.

② Atomic Claim

第二種 hyperscaler backend deployment 是 single-plane network，NIC 端使用 1.6T OSFP cages。
