Fibre optics and optical communications

Fibre optics and optical communications is the use of thin strands of glass for sending information encoded into light over long distances. Total internal reflection prevents light inserted into one end of the fibre from escaping through the sides. Transferring information optically in this way enables much higher transmission rates than using an electrical signal.
