Benefits of Twisted Pair Cable Construction



Invented by Alexander Graham Bell in 1881 for the telegraph market, twisted pairs were designed to reduce or minimize crosstalk between long cable lengths running in parallel. Known as differential mode transmission, the two wires carry equal and opposite signals and the destination detects the difference between the two. Interference signals tend to couple to both wires equally, producing a common-mode signal which is cancelled at the receiver when the difference signal is taken.



Color Info of Twisted Pair Cable


This method starts to fail, though, when the source of interference is close to the signal wires; the closer wire will couple with the noise more strongly and the common-mode rejection of the receiver will fail to eliminate it. In a situation like Ethernet cables, one pair can induce crosstalk in another and it becomes additive along the length of the cable. By twisting the wires at different rates, the crosstalk effect is negated. At each half twist, the wire nearest to the noise source is swapped. Providing the interfere source remains relatively uniform over the distance of a single twist, the induced noise will remain common-mode.

The twist rate (also called “pitch of the twist” and usually defined in twists per meter) makes up part of the specification for Ethernet cable. By altering the length of each twist, crosstalk is reduced.
