Transcript of Fibre Optic Cables

Fibre Optic Cables Fibre optics are thin cables that convert data into light so it can travel faster across great distances. Light is kept at the core of the cable, which is then overlaid with many more layers. The part of the cable that carries the data itself is very thin, so it needs protection to prevent being cut or sliced. Many of them can be bundled together for larger data delivery. The cables can be carried across long distances, and many of them are bundled together and kept at the at ocean floor. Optical fibre cables have revolutionized how data is transferred, and this technology is used in all sorts of various modes of communication, such as: Telecommunication by talking through phones, internet lines, and tv signals. Optical fibre cables were first invented
in the 1970s by Corning Glass Works, and since then they have been used in a wide range of applications. At first, they were extremely costly to be used in mass formations, but have now become cheaper. Optical fibre cables are also used in toys, and they can light up in many different colours. Optical fibres are a much better alternative to using standard copper wire, as it has many benefits over the other:
Less expensive than copper wire when dealing with long distances (saves you and your service providers money)
They have a much greater carrying capacity. Since optical fibres are thinner than copper wire, they can be bundled together much more easily.
Since they use light signals, they travel faster than those in copper, and don't interfere with other signals in the wire.
No electricity passes through optical fibres, so there is no hazard of a fire or other damage. So, what are they?
