In optical fiber communication, metal wires are preferred for transmission because the signals travel more safely. Optical fibers are also resistant to electromagnetic interference. Total internal reflection of light is used in the fiber optical cable. Unlike copper wires, which are limited by lower data transmission speeds, shorter transmission distances, and higher susceptibility to electromagnetic interference, fiber optic cables offer unparalleled performance and can cover much greater distances without bumping up against signal degradation. There are different types of fiber optic cables because each type is optimized for specific applications that have unique requirements for bandwidth, transmission distance, and environmental factors. A fiber-optic cable, also known as an optical-fiber cable, is an assembly similar to an electrical cable but containing one or more optical fibers that are used to carry light.
