Difference between Coaxial Cable and Twisted Pair Cable

Prerequisite – Types of Transmission Media

Coaxial Cable:
Coaxial Cable is a category of guided media that is used to perform transmission of large frequency signals. Coaxial cable constitutes of a solid conductor, three coats of insulation and a grounding conductor. In coaxial cables, inner solid conductor helps in transmitting the signals in the form of electrical signals. Coaxial cables are commonly used in internet connections, television signal distribution and radio transmissions.

Twisted Pair Cable :
Twisted Pair Cable is a category of guided media in which circuit is made by twisting two wires to perform transmission. Twisted pair cable constitutes of a combination of insulated copper wires. In twisted pair cable, metallic copper wire helps in transmitting the signals in the form of electrical signals. Twisted Pair Cable are mostly used in telephone networks and cable shielding.




The difference between Coaxial Cable and Twisted Pair Cable are as follows:

S.No. Coaxial cable Twisted Pair Cable
1. In coaxial cable, transmission of signals happens via inner conductor of cable. In twisted pair cable, transmission of signals happens via metallic conducting wire.
2. Coaxial cables are difficult to install and implement. While twisted pair cables are easy to install and implement.
3. Coaxial cable has finest noise protection as compared to twisted pair cable. In twisted pair cable, there is lowest noise immunity.
4. Coaxial cable supports a bandwidth of moderate range. Twisted pair cable supports a bandwidth of low range.
5. Applications of coaxial cable are in internet connections, television signal distribution and radio transmissions, etc. Applications of twisted pair cable are in telephone networks and cable shielding.
6. Cost of coaxial cable is comparatively expensive. Cost of twisted pair cable is less as compared to coaxial cable.
