Crossover Cable
Published by Admin on 2008/11/28 (235 reads)
A crossover cable is a cable that maps all output signals on one electrical connector to the input signals on the other connector, allowing two electronic devices to perform full-duplex communication.
Most commonly, the term refers to the Ethernet crossover cable, but other cables follow the same principle. It also allows devices to communicate without a switch, hub, or router.
Cross-Over cables are used to connect two computers directly through NICs without the use of a Hub or Switch or to uplink two or more hubs, switches or routers.
The Pins of the RJ-45 Connectors at both ends of a cross-over cable are connected as follows:
Only two pairs of wires in the eight-pin RJ-45 connector are used to carry Ethernet signals. Both 10BASE-T and 100BASE-T use the same pins, a crossover cable made for one will also work with the other.
