But before we delve into CPO's technology roadmap and its future deployment prospects, here is a brief introduction to this silicon photonics architecture and how it empowers artificial intelligence (AI), high-performance computing (HPC), and high-speed networking applications . But before we delve into CPO's technology roadmap and its future deployment prospects, here is a brief introduction to this silicon photonics architecture and how it empowers artificial intelligence (AI), high-performance computing (HPC), and high-speed networking applications . Base stations typically consist of Remote Radio Units (RRUs) and Baseband Units (BBUs), which are linked using optical modules and fiber optic cables. In 4G networks, common optical module types include 1. 5G, 6G, and 10G variants, facilitating efficient and stable signal transmission between. Co-packaged optics (CPO) technology, a key enabler for next-generation data center architectures, promises unprecedented bandwidth density and power efficiency by tightly integrating optical engines with switch silicon. But after nearly a decade of existence, where does this next-generation optical. need to manage large amounts of data quickly and efficiently is boosting the demand for high-speed data transfer in data centers. The emergence of Generative AI has further fueled the demand for high-speed data transfer such that nearly three-fourths of the data center traffic resides within da. Co-packaged optics (CPO) will play a fundamental role in improving the performance, efficiency, and capabilities of networks, especially the scale-up fabrics for AI systems. From Jensen Huang showcasing CPO switches at GTC 2025 to a wide range of vendors demonstrating optical engines integrated inside ASIC.
