Context Before

Meta will not be the only hyperscaler using 1.6T AECs for its VR200 deployments.

Evidence

We think xAI will use 1.6T AECs for both NIC-to-TOR and switch-to-switch connectivity at the leaf, spine and core layers.

Context After

It will be a single-plane network replacing most 1.6T transceivers at the switch boxes—and this can give Credo plenty of pricing power.

② Atomic Claim

SemiAnalysis 認為 xAI 將使用 1.6T AEC，同時支援 NIC-to-TOR，以及 leaf、spine、core 各層的 switch-to-switch connectivity。
