AI Data Center Interconnect 2026: CPO, Optical Interconnect and
Explore AI data center interconnect trends in 2026, including CPO, optical interconnect, OCS, and the real challenges slowing large-scale deployment.
Home / CPO optical modules and communication equipment
Co-Packaged Optics (CPO) is an emerging technology that integrates optical engines directly with electronic switching chips to enable higher bandwidth, lower power consumption, and improved signal integrity in next-generation data centers and high-performance computing systems. Today, data centers use a separate approach for optics and electronics, in which optical modules are connected to switches and routers through high-speed electrical interfaces. As data demands grow, these systems face limitations such as bandwidth constraints, latency issues, and space limitations. 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. g multiple highly integrated comp would give more power to switch ma formats will contribute to this growth.
