The entity in charge of defining PCI Express standards, PCI-SIG, has developed a new specification for cables that allow devices that use the PCIe interface to be interconnected. It is about the cables CopprLink which already have their specification for PCIe 5.0 and PCIe 6.0.
These cables are valid for both internal and external applications and promise signals of up to 32 and 64 GT/s. They will use the SNIA SFF-TA-1016 connector for internal component connections and the SNIA SFF-TA-1032 connector for external connections between equipment.
They can reach lengths of up to 1 meter to connect components both internally and in the form of peripherals. In fact, they can reach up to 2 meters in the case of external connections between racks.
Some examples that the PCI-SIG has commented on are the use of connections between CPU and storage, CPU to Memory, CPU to GPUs or accelerator cards and other types of external components.
The specification for CopprLink cables under PCI Express 7.0 is in development and will arrive later, although there are still no devices on the market with PCIe 6.0 or PCie 7.0, they are preparing for this standard to be compatible with future solutions.
