A twisted pair cable is a type of wiring in which two conductors are intertwined to cancel out electromagnetic interference from external sources and improve signal integrity. Central to modern network infrastructures, these cables are pivotal in transmitting data for both telecommunications and computer networking. What's meant by twisted pair cables and where are they found? Learn here about how twisted pair cables work, their types, and their applications. Learn about twisted pair cable, a type of wiring widely used in communication systems, including telephone lines, computer networks, and other electronic data transmission systems. Find out its history, structure, types, categories, uses, advantages, disadvantages, and comparison with other cable types. Definition: Twisted pair cable is special type cabling that is using in telephone communication and Ethernet network. This cable is made with two separate insulated copper wires, which are twisted together with each other as well as run in parallel form. The copper wires persist with 1mm in diameter.
