What power source is used in fiber optic cables for telecommunications

Unlike traditional copper wires that transmit data using electrical signals, fibre optic cables use light to send information. That conversion can be done with a photovoltaic cell. Power-over-fiber (PoF) is a technology in which a fiber-optic cable carries optical power, which is used as an energy source rather than, or as well as, carrying data. This is a crucial distinction that often leads to confusion. The light signals are the data. Fibre optic cables are a marvel of modern technology, transforming the way we transmit data and establishing themselves as a key player in broadband internet delivery.
