Optical fibres are used to transmit information over long distances and with high bit rates. Their benefits are numerous. First, the signal transmitted on the fibre is not disturbed by any electromagnetic wave created by power cables or electric machines. It also provides more security, as these cables can be fully dielectric. Furthermore, they are lightweight and space-saving due to their small diameter.
