Evidence

Each LPU has 4x100G lanes that go to the OSFP cages to connect LPUs across 4 racks

Context After

Nvidia’s CPO Roadmap

NVIDIA revealed its CPO Roadmap at the GTC Keynote 2026, with Jensen following up with additional commentary in the Financial Analyst Q+A meeting held the following day. Though many had their hopes up for CPO to be used for scale-up within the rack for Rubin Ultra Kyber, Nvidia’s focus was instead on using CPO to enable larger world size compute systems.

② Atomic Claim

每顆 LPU 有 4×100G lanes 連至 OSFP cages，以跨 4 個機櫃連接 LPU。

④ Canonical Entity Mapping

Role	Surface Label	Canonical Target
comparison_entity_0	LPU	04_knowledge_base/Groq LPU
comparison_entity_1	100G	100G
comparison_entity_2	OSFP	04_knowledge_base/OSFP (Octal Small Form-factor Pluggable)

⑤ Human Review

請在 Properties 逐項確認：

• 原文 → Atomic Claim 是否忠實
• Atomic Claim → Semantic Frame 是否忠實
• Canonical Entity mapping 是否正確
• Epistemic mode 是否保留原文語氣
