This report provides a comprehensive analysis of Co-Packaged Optics (CPO), encompassing various critical aspects: Market Dynamics: Examination of key players such as Nvidia, Broadcom, Cisco, Ranovus, and Intel, and the forces shaping the CPO landscape. Even as SerDes speeds increase, copper-based links struggle to deliver the required bandwidth per watt, once equalization and retiming overheads are factored in. Third, distance itself has become a problem: latency, energy per bit, and signal integrity degrade sharply with electrical reach. This integration significantly reduces the. As datacenters strive to meet escalating demands for efficiency and bandwidth, particularly with the integration of AI and ML technologies, optics is poised to play a crucial role in shaping the future of interconnect architecture and performance. The increasing investment in innovative. IDTechEx's report titled "Co-Packaged Optics (CPO) 2026 to 2036: Technologies, Market, and Forecasts" examines this transition in detail. It reviews recent advances in CPO technology, tracks emerging packaging approaches, assesses the strategies of leading companies, and provides long term market. OFC 2025 made one thing clear: The transition to Co-Packaged Optics (CPO) switches in data centres is inevitable, driven primarily by the power savings they offer. From Jensen Huang showcasing CPO switches at GTC 2025 to a wide range of vendors demonstrating optical engines integrated inside ASIC.
