All AI Data Center Interconnects Will Be Optical Within 5 Years
By Geoff Tate - 06 Apr, 2026 - Comments: 0

I spent several days at OFC (Optical Fiber Communications Conference) 2026 in LA. The crowds were huge and the enthusiasm intense. Long-time attendees noted the shift from telecom to data center AI in just a few years. Nvidia GTC 2026 took place simultaneously in San Jose. OFC and GTC are entangled because data center AI needs optical interconnect to keep compute fed. Optical interconnect... » read more
