Optical fibre communication is......

-An alternative choice that could replace copper wire transmission.

-The transmission process that includes the procedures of changing data into light and then changing it back to the original data.

-The structure of an optical fibre consists of layers, the outer layer which is the coating, the further layer called the cladding and the inner layer which is the core.

-The optical fibre relies on internal reflection for transmitting light.

-During the process of transmitting, a little amount of light/energy would be released outside of the fibre.

-There are three types of optical wire commonly use, for example: single mode, multimode and plastic optical fibre.

-The reason that Optical Fibres are now commonly used is because......

1.It is more energy saving.

2.It is more faster in transmitting.

3.It has a long life span.

4.It does not take up much space.

5.It is more environmentally friendly.
