Co-packaged optics (CPO) has been introduced as a promising technology to fulfill power consumption and bandwidth density requirements in the next generation of datacenters ecosystem. However, there is a need for an industry wide strategic roadmap to identify key limitations and challenges of both CPO and pluggable optics technologies and potentially define transition point and adoption rate from pluggable optics to CPO. In addition, different requirements need to be met to deliver a reliable, cost effective, and competitive solution for different platforms including HPCs and AI Clusters over a particular time horizon.

This workshop debates several controversial ideas to visualize the future directions by focusing on the key topics including a) coexistence of both technologies vs ultimate life time of pluggable optics, b) CPO realization difficulties vs innovative ultra-high speed pluggable optics challenges, c) industry readiness, concerns, applications, and adoption rate through this paradigm shift, d) cost trajectories, e) optical technologies (IMDD/coherent, parallel fiber/WDM, etc.), f) advanced light source development and integration, g) BW requirements for different future topologies/architectures relying on disaggregated compute and storage, and h) standardization. Different aspects of both solutions including high speed electrical interfaces, packaging, signal integrity, system integration, form factors, thermal managements, reliability, redundancy/serviceability, test/diagnosis, scalability are also discussed as important factors in this workshop.


To be determined.
