Advantage and disadvantage of twisted pair cable coxial cable and fiber optic cable?
The twisting of wires reduce crosstalk because when electrical current flows through a wire, it creates a small, circular magnetic field around the wire. When two wires in an electrical circuit are placed close together, their magnetic fields are the exact opposite of each other. Thus, the two magnetic fields cancel each other out. They also cancel out any outside magnetic fields. Twisting the wires can enhance this cancellation effect.
No. Coaxial cable is a single wire that has a thick coating around it. A common use of coaxial cable is for cable television. This is the cable that goes from the jack on the wall into your cable box. Twisted pair contains multiple cables which are split into pairs and twisted together. CAT5/CAT5e/CAT6 cable are all examples of twisted pair. There are a total of 8 wires inside. Every two wires are twisted together…
Unshielded Twisted Pair, or UTP, cable can receive unwanted interference and data from other close network cables. This is the largest disadvantage to UTP. The other disadvantage is that the signal being carried on the cable can leak to other nearby cables. Both of these conditions can be very detrimental to the network
The primary advantage of coaxial cable compared to twisted pair is the braided metal shield is very good at blocking electromagnetic signals from entering the cable and producing noise. And has also been used for long-distance telephone transmission, as the cabling within a local area network, and as a connector between a computer terminal and a mainframe computer.
