Nvidia announced its first CPO solution, which will be deployed in its scale-out switches. Just a few years later, CPO has moved from concept to real-world demo. While in Japan, NTT (Japan) has begun providing commercial samples based on its IOWN concept1. With major players moving to release products simultaneously, 2026 is likely to become a critical inflection point marking the start of competition for leadership in the next-generation AI infrastructure. XPO represents a new class of optical pluggable module designed specifically for next-generation AI data center fabrics. They are. From Jensen Huang showcasing CPO switches at GTC 2025 to a wide range of vendors demonstrating optical engines integrated inside ASIC packages at OFC 2025, CPOs are everywhere. However, it's worth noting that Andy Bechtolsheim, co-founder of Arista and a long-standing visionary in data centre.
