The PCI Special Interest Group (PCI-SIG) that owns and manages PCI specifications, yesterday announced the availability of the PCI Express External Cabling 1.0 specification, which extends the PCI Express (PCIe) interconnect architecture "outside the box."

The PCIe External Cabling specification provides guidelines for a practical cable length, but does not currently set a maximum cable distance.
