Optical Module CPO Switch

Home / Optical Module CPO Switch

Co-Packaged Optics (CPO) is an optoelectronic co-packaging technology that integrates an optical module (responsible for optical signal transmission and reception) and a switch ASIC (responsible for electrical signal processing) into the same physical package. NVIDIA's co-packaged optics (CPO) switches with integrated silicon photonics are the world's most advanced networking solution for the era of agentic AI. From Jensen Huang showcasing CPO switches at GTC 2025 to a wide range of vendors demonstrating optical engines integrated inside ASIC. This article provides a comprehensive overview of CPO optical modules, exploring their technology, benefits, challenges, and the pivotal role they play in future data centers.
