Context Before

While not part of the Rubin NVL72 rack, Spectrum-6 CPO enables even larger scale-out clusters with its doubled radix.

Evidence

The design retains the same features as Spectrum-5, with 8 IO chiplets surrounding the main switch die.

Context After

102.4T switching bandwidth is achieved with 512x 200G SerDes. 32 3.2T optical engines on the package convert these electrical signals to optical links, each with a detachable fiber connector.

② Atomic Claim

該 design 保留與 Spectrum-5 相同的特徵，由 8 個 I/O chiplets 環繞 main switch die。

• Epistemic Mode: ASSERTED
• Mapping Status: PARTIAL

③ Semantic Frame

  },
  "frame_type": "ATTRIBUTE",
  "qualifiers": {
    "condition_text": "Spectrum-5 在目前 canonical registry 中不存在，因此保留為 source text，不建立 canonical node；主詞承接前一條 Spectrum-6。",

    ],
    "temporal_mentions": []
  },
  "value": {

    ],
    "value_text": "8 個 I/O chiplets 環繞 main switch die；design 與 Spectrum-5 保持相同特徵。"
  }
}

④ Canonical Entity Mapping

Role	Surface Label	Canonical Target
entity	chiplets	04_knowledge_base/Chiplet architecture
context_node	Spectrum-6	Spectrum-6

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
• 最後選擇 review_action
