Explain Fiber-Optics cable.
A cable with central glass tube covered with protective shield which transmit data using photons is fiber optics cable. These cables transmit data through concentrated bursts of laser beams which are carried by bundles of hair thin glass fibers. They have benefits over electronic cables in transmission speed and volume. This technology has revolutionized telecommunication applications which used electronic cables. Fiber optics cables as free from electro-magnetic interference as well as wire tapping.
