Key optical components in CPO include laser transmitters, photodetectors, waveguides, modulators, and silicon photonic integrated circuits (PICs). Co-packaged optics (CPO) is a disruptive approach to increasing the interconnecting bandwidth density and energy efficiency by dramatically shortening the electrical link length through advanced packaging and co-optimization of electronics and photonics. CPO is widely regarded as a promising. 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. 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. For years, pluggable optics have been the industry standard, but they are becoming a bottleneck in terms of power, density, and speed. Introduction The CPO JDF plans to release three documents focused on different elements of Co-Packaged Optics (CPO): the. Commercialization has started for network switches based on co-packaged optics (CPO), which are capable of routing signals at terabits per second speeds, but manufacturing challenges remain regarding fiber-to-photonic IC alignment, thermal mitigation, and optical testing strategies.
