It is widely anticipated that next-gen 51.2 Tb/s switch ASIC will need co-packaged optics (CPO) to tackle the looming challenges in power consumption and bandwidth density. CPO is also promising to flatten current multi-layer switching architecture through a high-radix switch, and enable a large-volume application of fiber to the server (FTTS). This workshop is to stimulate extensive discussions on necessity and challenges to partially/completely replace pluggable solution, and to explore current CPO technology readiness and its future development direction in datacenters and beyond. The workshop will be debating and answering the following three topics:

Topic 1) Is CPO a nice-to-have or must-have solution within 3 years? Data center operators and system vendors will discuss their most concerned issues, and the potential applications (e.g., FTTS) CPO can enable or enhance?

Topic 2) What are the most recent technology breakthroughs in chip-level building blocks, e.g., SEDES, lasers, VCSEL vs. SiPh, parallel/WDM, DD/coherent, and PICs?

Topic 3) What are the progresses in system integration, including packaging, thermal management, optical connectivity, system-level testing and diagnosis, redundancy and serviceability, scalability, signal and power distribution co-design of optical integration with switch/DSP/logic ASIC, and relevant standard development?
