CABLE

LAN Technology  Cabling
A wireless LAN or WLAN is a wireless local area network, which is the linking of two or more computers without using wires. LAN utilizes spread-spectrum based on radio waves to enable communication between devices in a limited area, also known as the basic service set.

Types Of Cables

  •  Unshielded Twiested Pair (UTP) cable  

  •   Shielded Twisted Pair (STP) cable 

  •  Coaxial Cable 

  •  Fiber Optic Cable

  •  Wireless LANs


Unshielded Twisted Pair (UTP) cable







 



 The standard connector for unshielded twisted pair cabling is an RJ-45 connector
 










RJ stands for REGISTERED JACK, implying that the connector follows a standard borrowed from the telephone industry. This standard designates which wire goes with each pin inside the connector.


Shielded Twisted Pair (STP) cable







STP is to help provide a more reliable data communication, suitable for environments with electrical interference and consists of two individuals wires wrapped in a foil shielding.
  

Coaxial cable
 







The most common type is called barrel connector because of its shape. Coaxial connectors are familiar from cable TV and VCR hook-ups, which employ both threaded and slip-on styles.



Fibre Optics











The most common connector used with fibre optic cable is an ST connector. It is barrel shaped, similar to a BNC connector.


 Wireless












Wireless telecommunications is the transfer of information between two or more points that are not physically connected.


For Your Addition Notes:


UTP, STP and Coaxial Cable used current while Fiber Optic and Wireless used light.
