TYPES OF CABLES

-

A. TWISTED-PAIR CABLE


 
Is the common type of cable. It have eight individual copper wires bundled together and covered with an insulating material.

The copper wire is always color-coded with a plastic insulation and they are twisted in pairs for a total of four pairs.




a.  SHIELDED TWISTED PAIR (STP)



               


Often used in "noisy" environments where a shield of metallic foil is wrapped around each of the wire pairs, with an additional overall shielding to protect against excessive electromagnetic interference.


b. UNSHIELDED TWISTED PAIR (UTP)



   It is the most common form of twisted pair wiring. It is less expensive and easier to work with than STP.



B. COAXIAL CABLE





It is the standard media used by cable TV operators. It consists of a plastic insulator that separates the solid copper inner conductor and the woven copper braid outer conductor.


C. FIBER- OPTIC CABLE




It has a reflective coating that allows light beams to travel without outer interference.
