An optical fibre is made of extremely pure silica.
An optical fibre is thinner than a human hair and stronger than a steel fibre of similar thickness. It can carry thousands of times more information than a copper wire!
Optical fibre cables have the advantage of being lighter and taking less space than copper wire cables for the same information capacity.
In order to understand how an optical fibre works, we need to go back to the basics and introduce the properties of light.
