Context Before

This means that each node has 16 x 15 x 2 lanes for inter-node C2C and 2 x 15 lanes for inter-node FPGA which is a total of 510 lanes or 1020 differential pairs (for Rx and Tx).

Evidence

Therefore, the backplane is 16 x 1020/2 = 8,160 differential pairs – we divide by 2 as each device Tx channel is a corresponding device’s Rx channel.

Context After

② Atomic Claim

因此 backplane 共有 16×1020÷2＝8,160 differential pairs；之所以除以 2，是因為每個 device 的 Tx channel 對應另一個 device 的 Rx channel。

④ Canonical Entity Mapping

Role	Surface Label	Canonical Target
entity	backplane	Backplane

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
