Detailed explanation-1: -Fiber-optic cables transmit data via fast-traveling pulses of light. Another layer of glass, called “cladding, ” is wrapped around the central fiber and causes light to repeatedly bounce off the walls of the cable rather than leak out at the edges, enabling the single to go farther without attenuation.
Detailed explanation-2: -Li-Fi (Light Fidelity) is a mobile wireless communication technology that utilises light to transmit data between devices rather than radiofrequency.
Detailed explanation-3: -Light is used to transmit data in the optical fibre. Optical fibre communication holds light as the information carrier and optical fibre as the transmission medium for communication.
Detailed explanation-4: -LiFi technology uses led‟s for transmitting data. It is derivative of optical wireless communication technology using light from Led to deliver high speed communication. Visible light communication works by switching the Led off and on at very high speed, it can‟t noticed by the human eye.
