LAN Cables

There are 4 types of LAN cable:

  • UTP - Unshielded Twisted Pair
  • STP- Shielded Twisted Pair
  • Coaxial Cable
  • Fiber Optic Cable
- it has 4 pairs of wires inside the jacket
- each pair is twisted with a different number of twists per inch to help eliminate interference from adjacent pairs and other electrical devices.

- is type of cable that consist of individual wires wrapped in a foil shielding to help provide a more reliable data communication.

- has single copper conductor as its center
- plastic layer provide insulation between the center conductor and a braided metal
- metal helps to block outside interference from fluorescent light, motors and others computers

- consists of center glass core surrounded by several layers of protective materials
- it transmit light rather than electronic signal eliminating the problem of electrical interference.
- able to transmit signals over much longer distance than coaxial and twisted pair.
