TYPES OF CABLE

What Are The Types Of Cables?

A. Twisted Pair

 

 a cable consisting of two wires twisted around each other, used especially for telephone or computer applications.

 1. STP (Shielded Twisted Pair)

  

 a special kind of copper telephone wiring used in some business installations. An outer covering or shielded is added to the ordinary twisted pair telephone wires; the shield functions as a ground.

 2. UTP (Unshielded Twisted Pair)

 are widely used in the computer and telecommunications industry as Ethernet cables and telephone wires. In an UTP cable, conductors which form a single circuit are twisted around each other in order to cancel out electromagnetic interference (EMI) from external sources.

B. Coaxial

 

 Coaxial cable, or coax, is a type of electrical cable that has an inner conductor surrounded by a tubular insulating layer, surrounded by a tubular conducting shield. Many coaxial cables also have an insulating outer sheath or jacket. 

C. Fiber Optic

 Fiber optic cable is a high-speed data transmission medium. It contains tiny glass or plastic filaments that carry light beams. Digital data is transmitted through the cable via rapid pulses of light.

 And now, let's talk about the difference between Straight-Through Cable and Crossover Cable.

A Straight-Through Cable  

  

 Is a type of twisted pair cable that is used in local area networks to connect a computer to a network hub such as a router,

While a Crossover Cable 

 

 Is a type of Ethernet cable used to connect computing devices together directly. Unlike straight through cable, crossover cables use two different wiring standards: one end uses the T568A wiring standard, and the other end uses the T568B wiring standard.
