Ayar Labs raised $500M at $3.75B with NVIDIA, AMD, and ARK Invest, totaling $870M for co-packaged optics that replace copper interconnects with light. This solves AI's critical bottleneck: copper degrades beyond 100 Gbps and maxes at 2 meters, while optical delivers 8 Tbps over longer distances efficiently. As hyperscalers invest hundreds of billions, optical becomes essential for GPU clusters copper cannot support.
