01
The problem
AI workloads require high-bandwidth, low-latency connectivity to link thousands of GPUs across racks into unified clusters. Copper-based interconnects face limitations in bandwidth density, power efficiency, and scalability, creating bottlenecks in hyperscale AI infrastructure.

02
The product approach
Ayar Labs’ TeraPHY optical engine replaces copper interconnects by integrating optical connectivity directly into chip packages. This enables high-bandwidth, low-latency communication between GPUs across racks, using an optical fabric to unify clusters.

03
What stands out
Unlike traditional copper interconnects, Ayar Labs’ CPO solution uses a remote light source (SuperNova) in an industry-standard ELSFP form factor, paired with TeraPHY optical engines. This combination is designed to eliminate bandwidth bottlenecks while maintaining compatibility with existing manufacturing and packaging flows.
