Fiber optics work by using total internal reflection to guide light through thin glass or plastic fibers. Light entering the fiber at angles greater than the critical angle reflects off the fiber walls, bouncing along the fiber without escaping. Unlike traditional metal wires that transmit electricity, fiber optic cables transmit light, making them capable of delivering higher bandwidth over longer. , and complete immunity to electrical interference. That makes it ideal for high-data-rate systems such as Gigabit Ethernet, multi- media, Fibre Channel, or any other network that requires the transfer of large, bandwidth-co s offer far greater distances than copper links do.
