An optical fiber is a thin, flexible strand of glass or plastic that transmits data as pulses of light, enabling high-speed, long-distance communication for internet, phone, and TV, working on total internal reflection to send signals with minimal loss and immunity to electromagnetic interference. These hair-like fibers have a central core and surrounding cladding, allowing light to bounce internally along the length of the fiber.
