CopprLink specifications for PCIe 5.0 and 6.0 copper cables
Cette publication existe aussi en Français
A new specification will extend PCI Express standard technology for high speed interconnect over copper cables.
The PCI-SIG has released the CopprLink Internal and External Cable specifications for signaling at 32.0 and 64.0 GT/s
This uses well-established industry standard connector form factors maintained by the Storage Networking Industry Association (SNIA) for storage, data centres, artificial intelligence, machine learning and disaggregated memory.
“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.”
The Internal Cable specification supports PCIe 5.0 and 6.0 technology signaling at 32.0 and 64.0 GT/s with SNIA SFF-TA-1016 connectors with a maximum reach of 1m for motherboard-to-add-in-card, motherboard-to-backplane, chip-to-chip and add-in-card-to-backplane in a self-contained server platform node.
The External Cables Specification covers the SNIA SFF-TA-1032 connector form factor and provides a 2m reach for rack-to-rack connections, CPU-to-storage, CPU-to-memory, CPU-to-accelerator, and accelerator fabrics in disaggregated server platform nodes.
The CopprLink Internal and External Cable specifications are now available for PCI-SIG members to download at www.pcisig.com.
