Eric Litvin: Calibration Quality Defines 800G Optical Value

Eric Litvin of Luma Optics argues calibration quality, not raw speed, defines 800G optical interconnect value for AI clusters. Read why it matters.

As AI clusters grow denser and link rates climb, a single failed optical link can stall multi-node training jobs, making reliability-per-watt and calibration quality critical to operational efficiency. Litvin's argument signals a shift in how optical interconnect should be evaluated: throughput specifications alone are insufficient. For AI infrastructure buyers, the total cost of ownership increasingly hinges on failure prevention and diagnostic intelligence rather than raw speed, a change that could reshape vendor selection and data center design.
