Leadership Comments

“AI infrastructure is rapidly outgrowing the capabilities of traditional optical interconnect architectures,” said Nariman Yousefi, co-founder and CEO of Celero Communications. “Our 2nm silicon validation demonstrates that coherent technology can deliver the bandwidth density, power efficiency and scalability required for the next generation of AI networks.

“Networking is now growing faster than compute, and connectivity is one of the most critical challenges in scaling AI infrastructure,” said Gavin Baker, Managing Partner & Chief Investment Officer at Atreides Management. “The transition from PAM4 to coherent represents a fundamental shift in how the next generation of scale-up, scale-out and scale-across AI systems will be connected.
