Nvidia unveils OOI CPO prototype for post-2028 AI needs

Nvidia has unveiled a prototype of its next-generation co-packaged optics (CPO) technology, Optics-on-Interposer (OOI), at SEMICON West 2026. The design moves the optical engine from a conventional organic package substrate to the silicon interposer carrying the compute chips, increasing bandwidth density and reducing power consumption for future AI system interconnects.
