- 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.
