Coherent plans a September 21 PhotonLink unveiling. Its announcement leaves engineers with questions about configurations, workloads, and energy accounting.
The 2026 sampling, production and supply announcements make serviceability, energy boundaries and replacement responsibility central to evaluation.
The August paper addresses stored parameters and intermediate states; the available evidence does not support a whole-system efficiency ranking.
The March Passage announcement concerns data movement; its evaluation platform keeps measured bandwidth separate from efficiency targets.
The May announcement advances co-packaged optical networking while leaving shipment timing and workload gains as distinct questions.
A benchmark comparison needs compatible tasks, precision, accuracy targets, baselines, and energy boundaries.
An efficiency figure needs a workload, precision, and system boundary before it can describe real computing impact.
Moving data with light and performing a computation with light are related architectures, not interchangeable claims.
