Wiring

• Telephone Twisted Pair

  • Unshielded and susceptible to noise
  • Not for higher data rates or long distances
  • Inexpensive

• Coaxial Cable

  • Central core with shield around it
  • Shield insures radio frequency noise is not generated
  • High data rates at long distances

• Fiber Optic Cable

  • Light signals transmitted by light emitting diodes are immune to electrical and magnetic noise
  • High data rates at long distances
