Applications of fibre optics in communication
Optical communication gathers signals from computers and mobile phones at the base stations and network providers of local communication operators, and then transmits them around the world through optical fibers in submarine cables. Internet, mobile phones, IP phones, and other devices that use the Internet, connect everyone to their region, to entire countries, and even to the global communications network.
