PCI-SIG® 推出支持PCIe® 5.0、6.0 技术指令的 CopprLink™ 电缆规范

The specifications extend PCIe channel reach for applications including storage, data centers, artificial intelligence, machine learning and disaggregated memory

BEAVERTON, Ore.-- May 01, 2024 -- 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.”
