The next-gen cabling PCIe connections

PCIe Express through cables, just faster than OCuLink.



Although it may seem that OCuLink technology is gaining popularity, it is no longer developed, and the OCuLink Work Group ceased work in 2021. However, PCI-SIG did not unveil anything that would replace these cables, which were primarily designed for data centers but are now commonly used for consumer external GPUs and storage.

Today, PCI-SIG has unveiled the specs for CopperLink, the next-generation cabling based on PCI Express. These cables will enable new connection types for modern storage, data centers, and AI systems, including external and internal connections. It is not aimed at consumers, but nothing should stop companies from using it for such purposes.

Within PCI-SIG, there are three workgroups: the Electrical Work Group (EWG), the Cabling Work Group (CWG), and the Optical Work Group (OWG). The latter’s work is not yet finished, but the idea is to create optical cabling for even faster systems later.
