twisted pair
A pair of individually insulated conductors (wires) twisted together and treated as an entity in the transmission of electrical signals or power (e.g., from an electronic power supply to a circuit). Note 1: In communications cables, the twisted pair is usually if not always composed of two individually insulated solid conductors (wires). In other applications, e.g., in a power-supply application, each of the insulated conductors may consist of stranded wire. Note 2: Because the wires are twisted together, interfering signals tend to create opposing electromagnetic forces at frequent intervals, reducing the effect of the interference on the signal or power supply voltage being conducted. Note 3: Twisted pairs may be used for bit rates up to 1 Mb/s over short distances (<100 m) and lower bit rates over longer distances. More sophisticated driver and receiver circuits facilitate similar or higher data rates over longer distances. Note 4: Unshielded twisted pairs (UTPs) are used extensively in telephone networks and in many data communications applications.
