Long Distance Communications
We have talked about:

  • guiding light and the associated problems

  • detecting light

  • generating light

    •
    It is now time to talk about transmitting light over long distances.

    Signals transmitted over long distances weaken and need to be re-amplified at regular intervals. This is true whether using copper wire, radio waves or optical fibres.
