Twisted pair wire is an electrical wiring technology used for data transmission and telecommunication purposes. It has been around for decades, and people use it in various applications such as networking, signal processing, and power transfer. The technology allows for efficient signal transmission by allowing multiple wires to be twisted together at regular intervals to reduce crosstalk between two or more pairs of wires. Twisted-pair wire also offers several benefits, including better signal quality, increased speed, reduced interference, low cost, and greater flexibility.
