Context Before

Increased overall network reliability is another compelling point. Transceivers can be unreliable, with

Evidence

a large cluster certain to have ongoing link flaps.

Context After

Meta’s study presented at ECOC showed strong reliability results over 15M 400G port-device hours, which is about equivalent 15 CPO switches tested for 11 months in a lab. It is an encouraging start—but we think this point could get stronger with more in-field test deployments.

② Atomic Claim

在大型 cluster 中，持續發生 link flaps 幾乎是不可避免的。

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
