At GTC 2025 on March 18, 2025, NVIDIA unveiled its revolutionary silicon photonics technology, replacing traditional pluggable optical transceivers with co-packaged optics (CPO). OFC 2026, the world's largest annual gathering for optical networking and communications professionals, wrapped up on March 19 in Los Angeles, drawing nearly 18,000 attendees from across the global optical ecosystem. Five days of major product announcements, technical exchange, and live. Silicon Photonics is an emerging technology that is bringing a paradigm shift in the field of single mode fiber-optic communications. Silicon Photonics leverages mature CMOS wafer fabrication and packaging infrastructures to deliver high bandwidth, low power transceivers.
