The specifications extend PCIe channel reach for applications
including storage, data centers, artificial intelligence, machine
learning and disaggregated memory
PCI-SIG®, the organization responsible for the widely adopted
PCI Express® (PCIe®) standard, today announced the release of the
CopprLink™ Internal and External Cable specifications. The
CopprLink Cable specifications provide signaling at 32.0 and 64.0
GT/s and leverage well-established industry standard connector form
factors maintained by SNIA.

“The CopprLink Cable specifications integrate PCIe cabling
seamlessly with the PCIe electrical base specification, providing
longer channel reach and topological flexibility,” said Al Yanes,
PCI-SIG President and Chairperson. “The CopprLink Cables are
intended to evolve with the same connector form factors, scale for
future PCIe technology generations and meet the demands of emerging
applications. The Electrical Work Group has already begun
pathfinding work on CopprLink Cables for PCIe 7.0 technology at
128.0 GT/s, showcasing PCI-SIG’s commitment to the CopprLink Cable
specifications.”
