Co-Packaged Optics (CPO)

What is co-packaged optics (CPO)? A technology in which optical components are integrated into a single package.

Co-packaged optics (CPO) is a technology in which optical components are integrated into a single package. CPO modules, which are a replacement strategy for pluggable optics, are best suited for large Ethernet network switches. This is because they can improve the performance and power efficiency of data centers. Manufacturing CPO modules is more expensive and challenging than manufacturing traditional optical modules, and their adoption may require changes to network infrastructure and design.
