Context Before

Increased overall network reliability is another compelling point. Transceivers can be unreliable, with a large cluster certain to have ongoing link flaps.

Evidence

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.

Context After

It is an encouraging start—but we think this point could get stronger with more in-field test deployments.

② Atomic Claim

Meta 在 ECOC 發表的研究顯示，經過 1,500 萬個 400G port-device hours 測試後，CPO 顯示出良好的可靠性；這約等同於 15 台 CPO switches 在實驗室中測試 11 個月。
