What type of cable uses light guided through thin glass or plastic tubes to transmit data?

Fiber-optic cable uses light guided through thin glass or plastic tubes to transmit data. This technology relies on the principle of total internal reflection, allowing light signals to travel long distances with minimal loss and high data speed. Fiber-optic cables are capable of handling much higher bandwidth compared to traditional cables, making them ideal for high-speed internet and telecommunications. The material properties of glass or plastic enable the efficient transmission of data as light waves, which are less susceptible to interference from electromagnetic noise compared to electrical signals carried by other types of cables. This fundamental characteristic of fiber-optic technology makes it a preferred choice in modern communication systems for both residential and commercial uses.
