Light penetrates fiber optic cable
In fiber optics, the fiber acts as a waveguide wherein the light is confined to propagate down the length of the cable. This technology relies on the transmission of light through thin strands of glass or plastic, allowing for efficient data transmission over long distances. The core is composed of highly purified silicon dioxide (SiO2) with very small trace amounts of “dopants” (such as Germanium), added to adjust the index of refraction for optimum optical transmission. Different diameter cores are available for different. These strands, known as fibre optic cables, have revolutionised telecommunications because they transmit information using pulses of light. Unlike copper wires, which send electrical signals and suffer from resistance and interference, fibre optics offer orders of magnitude more bandwidth and. These cables are used mainly for digital audio connections between devices. -
