What types of wires are cables and optical fibers
In the landscape of network infrastructure, three primary cable categories dominate connectivity: twisted-pair copper cables, coaxial cables, and fiber optic cables. 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. These cables are used mainly for digital audio connections between devices. 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. The optical fiber elements are typically. Why are there different types of fiber cable?
