Ayar Labs/TeraPHY optical I/O

Ayar Labs joined NVIDIA's NVLink Fusion ecosystem, making its co-packaged optics electrically and optically compatible with NVIDIA's rack-scale AI systems. Customers can connect mixed chips inside NVIDIA-based AI racks over light instead of copper; NVIDIA participated in Ayar's recent $500 million Series E.

• Co-packaged optics provide high-bandwidth, low-latency, power-efficient connectivity within NVIDIA rack-scale infrastructure.
• NVIDIA participated in Ayar's $500 million Series E funding round; other investors include AMD, Applied Ventures, and MediaTek.
• Preserves customer investments in NVLink architecture while enabling heterogeneous AI factories.
