What is OCP Open Silicon Photonics for AI Systems Architecture Blueprint?

OCP Open Silicon Photonics for AI Systems Architecture Blueprint is an open technical specification for integrating silicon photonic interconnects alongside compute and switch silicon in AI data center systems, defining common interfaces and packaging practices for optical input/output. It is intended to let hardware vendors build interoperable co-packaged optics components for high-bandwidth, low-power links between accelerators, switches, and memory in large-scale AI clusters, reducing reliance on proprietary optical interconnect designs.
