2026 OCP EMEA Summit
Title: Open AI Fabric: An OCP MHS Reference Architecture for Modular Photonic Switching
Abstract: Scaling AI clusters to thousands of accelerators demands fabrics that transcend traditional silicon and photonics boundaries. We present an open reference architecture for next-gen AI fabrics, extending OCP MHS principles to support chiplet driven ecosystems and software-defined control via SAI.
We propose a 2 Open Rack Unit (ORU) switch design aligned with IEEE 802.3/OIF roadmaps for 200G-per-lane signaling. The architecture supports low-latency scale-up and scale-out while addressing the shift toward disaggregated chiplet designs. Crucially, a RAS-first approach uses OIF-compliant ELSFP modules to decouple laser thermals from switch ASICs. This facilitates field-replaceable light sources alongside CPO, fostering a robust, open component ecosystem.
