Cabled PCI Express
From Wikipedia, the free encyclopedia
The name used by PCI-SIG (PCI Special Interest Group) is PCI Express External Cabling. The most commonly used name is External PCI Express (28400 Google-hits, 2008-03) or shortned External PCIe. Another name used is Cabled PCI Express (2400 Google-hits, 2008-03) or shortned Cabled PCIe.
The PCI Express External Cabling 1.0 Specification, released by PCI-SIG in February 2007, extends PCI Express “outside the box”. It establishes a standard method of using PCI Express over a cable by defining cable connectors, copper cabling attributes and electrical characteristics, connector retention, identification and labeling.
- It conforms to the PCI Express 1.1 Base and electromechanical specifications, enabling high data rates between PCI Express subsystems.
- Standard cables and connectors have been defined for x1, x4, x8 and x16 links (pronounced “by one,” “by four” and so on).
- The cable provides sideband signaling to maintain compatibility with existing silicon and software.
- The cabled PCI Express specification offers guidelines for a practical cable length but does not currently set a maximum cable distance.
