At today’s Hot Interconnects online event, Nubis Communications CTO Peter Winzer warned that AI and HPC clusters are increasingly I/O bound, with interconnect performance unable to keep pace with compute. Winzer introduced Co-Packaged Optics Extensions (CPX) as a pragmatic path to bring co-packaged optics into mainstream deployment.
At the recent OIF 448G Workshop, Peter Winzer, Founder and CTO of Nubis Communications, emphasized the urgent need for holistic electrical-optical integration as the industry approaches 448G per-lane signaling.
Ericsson and Nubis demonstrated at ECOC 2024 how co-packaged optics can enable high capacity and low energy consumption in future RAN networks, showcasing key features like high-temperature operation, standard optical fiber compatibility, and automated eye-safety.
The key differentiator is the ability to leverage the LR SerDes generally already aboard today’s high-performance ASICs to directly drive the optical interconnect engine.
