What do twisted pairs in cabling help to reduce in communication systems?

Twisted pairs in cabling are specifically designed to reduce crosstalk between the individual pairs of wires within the cable. Crosstalk refers to the undesired transfer of signals between adjacent pairs of wires, which can lead to data errors and communication issues. By twisting the pairs together, the electromagnetic interference caused by nearby pairs is minimized. This design helps maintain the integrity and quality of the signal being transmitted, making it a crucial aspect of twisted pair technology used in various communication systems, including telephony and Ethernet networks.

While interference from external sources, network congestion, and signal attenuation are important considerations in communication systems, they are typically addressed through different methods or technologies and are not the primary focus of twisted pair design.
