Twisted Pair Cable
TWISTED PAIR. A line consisting of two insulated wires twisted together to form a flexible line without the use of spacers. Different types of cables will vary the wire gauge [AWG] for the inner conductors and there twist, the number of times the wires are twisted per inch. The Braid or shield [outer conductor in the diagram] also varies with different cables by coverage and number of braids. The shield may also be a foil instead of a braid.
Shielded Twisted Pair Cable
Electrical Characteristics to account for; Characteristic Impedance, Attenuation, and Capacitance.
Twisted pair cables may be shielded or un-shielded. The diagram above shows an example of a shielded twisted pair cable [STP]. Twisted pair cables with out a shield are called Unshielded Twisted Pairs [UTP]. By definition a twisted pair cable is a multi-conductor cable, and normally a round cable. Also called a Paired Cable.
Ribbon Cable is also available as Twisted Pair, as a number of Twisted Pairs glued together into a flat cable [normally un-Shielded].
Also refer to Twisted pair Attenuation Graph for 24 AWG
Military Standards: MIL-C-17
Interface Bus Standards: EIA-485 is one of many electrical interface buses that required Twisted Pair cables.
CanBus may use either a STP or an UTP cable depending on the application [the level of noise in the environment].
Table that provides a number of Cable Bus Standards using Twisted Pair Cable and which use STP or UTP cable interfaces.
COST: There is the added cost of the shield for Shielded Twisted Pair Cable, so Un-Shielded Twisted Pair Cable is cheaper to implement. Systems that require higher reliability or that reside in high noise environments will tend toward the higher cost Shielded Twisted Pair Cabling.
