AIchip Applied sciences and Ayar Labs unveiled a co-packaged optics (CPO) answer for multi-rack AI clusters, offering prolonged attain, low latency, and excessive radix. The joint growth tackles AI infrastructure data-movement bottlenecks by changing copper interconnects with CPO in large-scale accelerator deployments.
The providing integrates Ayar’s TeraPHY optical engines with AIchip’s superior packaging on a standard substrate, bringing optical I/O on to the AI accelerator interface. This permits over 100 Tbps of scale-up bandwidth per accelerator and helps greater than 256 optical scale-up ports per machine. TeraPHY can also be protocol agnostic, permitting versatile integration with customer-designed chiplets and materials.
The co-packaged answer scales multi-rack networks with out the facility and latency penalties of pluggable optics by shortening electrical traces and inserting optical I/O near the compute core. With UCIe assist and versatile protocol endpoints on the package deal boundary, it integrates alongside compute tiles, reminiscence, and accelerators whereas sustaining efficiency, sign integrity, and thermal necessities.
Each corporations are working with choose clients to combine co-packaged optics into next-generation AI accelerators and scale-up switches. They’ll present collateral, reference architectures, and construct choices to certified design groups.
