Long Distance Communication

• What are the advantages of optical fibres in long distance communication?

  Signals aren't interfered by atmospheric interference (Weather)

  Difficult to intercept signals
• What are the disadvantages of optical fibres in long distance communication?

  Requires point-to-point connection between transmitter and reciever
• What are the advantages of satellites in long distance communication?

  Microwaves travel faster in air than infrared or visible light does in glass
• What are the disadvantages of satellites in long distance communication?

  Easier to intercept

  Can be affected by atmospheric interference (Weather)

  Signal strength can be limited by orbit of satellite

  Expensive to build and launch them
