Twisted pair cable

Twisted pair cable is one of the most commonly used communication media for network cabling. It consists of two separate copper wires that are covered by insulating material each as plastic and are twisted together to from a cable. One of the wires is used to carry single to the receiver. And other is used only as ground reference. The telephone cable wiring uses twisted pair show a twisted pair cable
Coaxial cable is also reference to as coax it carries signal of higher frequency ranges than twisted pair cable coaxial cable consists of a single solid copper wire which is called is called the inner conductor. Usually the inner conductor is surrounded by three layers
An insulating material which covers the inner conductor.
An outer conductor of solid metal foil shields
An insulating material. Which covers the inner conductor
The whole cable is protected by an external plastic covers. The structure of coaxial cable is shown in
Coaxial cable can be used for voice and data transmission with very high very frequency the data transmission speed of coax is from 10 maps 2000mbps
A fibre optic cable is made of glass or plastic and transmission signals in the form of light a fibre optic cable consists of tube of glass or thin glass fibre through which data is transmission as pulses of light. A typical optical fibre consists of a very narrow strand or fibre of glass called the core it is as thin as a human hair the core is surrounded by a concentric layers of glass called cladding. Fibre optic is shown in
The fibre optic cable is becoming more popular New a day's telephone internet and television companies are replacing more popular New are replacing their existing cables with fibre optic cable. The data transmission speed is very high became fibre optic transmission speed is up to billions bits per second.
