• Made of thin strands of silicone fibre

  • Transmission occurs at very high light wave frequencies

  • Allows for much greater transmission rates

  • Light waves are created by laser

  • Uses a monomode technique where a single stream of light travels down each fibre

Advantages of using fiber optic cable to transmit telecommunications signals.

  • Transmission is at light frequencies which are much higher than radio frequencies.

  • This means that much greater quantities of information can be transmitted.

  • Has good corrosion resistance

Why copper-based broadband is widely used despite the advantages of using fibre-optics.

  • Much of the world’s telecommunications infrastructure is still based upon copper wires.

  • Therefore, the cost of replacing all this copper wire with fibre-optic cable is high and would also require time. This means that there is a need for broadband systems based upon copper wire.
