What are the causes of twisted pair winding of network cables?

A twisted pair can serve as a flat line in a balanced circuit which enables the reduction of noise currents induced on the line due to the coupling of electric or magnetic fields.

The concept is based on the principle that the currents induced in the two wires are almost identical. Twisting the cables guarantees that they are equidistant from the interfering source on average, resulting in equal impact. Consequently, the noise generates a common-mode signal that can be eliminated at the receiver by solely detecting the difference signal, representing the desired signal.

Two insulated copper wires are twisted together at a specific density, and the waves radiated by each wire in transmission will be canceled out by the waves emitted from the other wire, effectively reducing the degree of signal interference.

It is designed to reduce crosstalk, signal interference and other noise.

The main purpose of this is to reduce the distributed capacitors between wires, reduce the serial interference between transmission loss and wires pairs, and ensure the transmission speed and transmission distance of the network cable.
