Context Before

Increased overall network reliability is another compelling point.

Evidence

Transceivers can be unreliable

Context After

, with a large cluster certain to have ongoing link flaps. 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.
