PCI-SIG has announced CopprLink internal and external cable specifications for PCIe 5.0 and PCIe 6.0 interconnections. These new CopprLink-branded cables are designed to enable high-performance cabled connections for AI, storage, and data center applications at 32 GT/s and 64 GT/s data rates. Meanwhile, PCI-SIG is already working on standardization of cabled connections for PCIe 7.0 at 128 GT/s.
Under the CopprLink umbrella, PCI-SIG introduces two distinctive cable standards for internal and external PCIe 5.0 and PCIe 6.0 interconnections at 32 GT/s and 64 GT/s data transfer rates in data centers. In both cases, PCIe cables are designed to add versatility and length to PCIe interconnections, as very thin board traces tend to lose signal over distances longer than 4 (in the case of PCIe 5.0) and 3.4 inches (in the case of PCIe 6.0).
