Transmission Medium in Data Communication

What is Twisted Pair Cable?

• Twisted Pair Cable is a type of cable made from a single conductor

• Twisted Pair Cable is a type of wiring in which two conductors are twisted together to reduce electromagnetic interference and crosstalk. It is commonly used in Ethernet networks.

• Twisted Pair Cable is not suitable for reducing electromagnetic interference

• Twisted Pair Cable is only used for power transmission
