Evaluation of CPO Performance and Pluggable Optics Health for Reliable AI Infrastructure#

Speakers: Siamak Amiralizadeh (Meta), VIRAL LOWALEKAR (Meta)

• Why: CPO is the biggest pending change in DC physical-layer architecture, and the honest questions are reliability, availability, and serviceability — exactly what Meta claims to test here, with multi-month methodologies rather than lab anecdotes.
• What: Meta's comprehensive evaluation of co-packaged optics against current pluggable transceivers, plus their multi-month reliability testing methodology for both current and next-generation optical technologies (including CPO) to enable robust link-failure detection and long-term optical reliability. (from abstract only)
• How: Power/cost optimization assessment of CPO (optics integrated on-ASIC) against improving pluggables, combined with systematic multi-month reliability testing across Meta's diverse transceiver fleet supporting AI/ML connectivity.
• Where applicable: Meta datacenter fleet and AI/ML connectivity — the results should be interpretable industry-wide since CPO tradeoffs are physical, but the failure-detection tooling is Meta's own.
