| Fibre-Optic Cables are cables that are made of extremely thin strands of glass or other material which is transparent and capable of carrying beams of light. Data can be sent through fibre-optic cables at the speed of light, due to the fact that they are light-based. A laser transmitter sends the signal and it is translated back into data when it reaches the end and this is used by a computer. Fibre-optic cables are useful as they are not able to be interfered with by noise or vibrations, the only downside to them is that they are very fragile. Due to this they are usually installed underground but this is expensive and mending broken fibre-optic cables is a difficult, expensive and time consuming process. |
