Optical fiber communication transmits information as light pulses through thin strands of glass or plastic fiber.
It offers enormous bandwidth, low loss and immunity to electromagnetic interference, forming the backbone of modern internet and telecom networks.
Light travels through the fiber core by total internal reflection, bouncing off the boundary with the lower-refractive-index cladding. A transmitter (LED or laser diode) converts electrical signals to light, and a photodetector at the receiver converts light back to electrical signals.
Single-mode fiber carries one light path over long distances, while multimode fiber carries several paths over shorter distances.
