High-Speed Cable Solutions for PCIe® 5.0 Technology

High-Speed Cable Solutions for PCIe® 5.0 Technology

PCI-SIG®, the organization responsible for the widely adopted PCI Express® (PCIe®) standard, announced the release of the CopprLink™ Internal and External Cable specifications on May 1st. These specifications extended the applications of PCIe channels, including applications such as storage, data center, artificial intelligence, machine learning and disassemble memory, etc.


It is reported that CopprLink™ cables can offer 32.0 GT/s (PCIe 5.0) and 64.0 GT/s (PCIe 6.0) data rates and utilize the SNIA standard connector form factor, which is a perfect blend of PCIe cabling and PCIe electrical base specification, providing longer channel reach and topological flexibility.

“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.” Al Yanes, PCI-SIG President and Chairperson said.
