Crossover Cable

A crossover cable connects two devices of the same type, for example DTE-DTE or DCE-DCE, usually connected asymmetrically (DTE-DCE), by a modified cable called a crosslink. Such distinction of devices was introduced by IBM.

The crossing wires in a cable or in a connector adaptor allows:

  • connecting two devices directly, output of one to input of the other,
  • letting two terminal (DTE) devices communicate without an interconnecting hub knot, i.e. PCs,
  • linking two or more hubs, switches or routers (DCE) together, possibly to work as one wider device.

Ethernet Crossover Cable - Overview
... When a terminal device is connected to a switch or hub, this crossover is done internally in the switch or hub ... A standard straight through cable is used for this purpose where each pin of the connector on one end is connected to the corresponding pin on the other connector ... to another without the use of a switch or hub, but in that case the crossover must be done externally in the cable or modular crossover adapter in a manner similar to how the null modem was used to directly ...
Ethernet Cables - Cabling
... brown Twisted-pair Ethernet standards are such that the majority of cables can be wired "straight-through" (pin 1 to pin 1, pin 2 to pin 2 and so on), but others may need to be wired in the "crossover" form (receive ... Since 10BASE-T and 100BASE-TX need only two pairs and Category 5 cable has four pairs, it is possible, but not standards compliant, to run two network connections or use spare pairs for PoE (Power over Ethernet) (or a ... It is conventional to wire cables for 10- or 100-Mbit/s Ethernet to either the T568A or T568B standards ...
