  • Connectors and mating connectors are connected in a conventional manner to shielded twisted pair cables, the cables have a shield.

  • Twisted wire pairs As twisted pair cables (or cables) with twisted wire pairs are referred to in telecommunications, communications and computer technology cable types in which the wires are twisted in pairs. Wire pairs can be stranded in a cable with different lay length and different directions of rotation in order to minimize crosstalk between the wire pairs. Twisted wire pairs offer better protection against electrical and magnetic interference fields than parallel wires. Due to the twisting of the wire pairs, influences from external fields mostly cancel each other out. Twisted wire pairs are intended for balanced signal transmission, which is less sensitive to common mode noise due to common mode rejection. Twisted pair cables with twisted Wire pairs have been used for a long time for signal and data transmission. Established and preferred, therefore, appropriate cables for all types of signal transmission are used, including in the stationary network technology.
