In essence, while optical fiber forms the core technology enabling high-speed data transmission, optical fiber cables are the infrastructure that harnesses and protects these fibers. The optical fiber is the main medium for the transmission of information, so before the study of optical fiber communication, we need to know the optical fiber structure. 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. But strictly speaking, the two are different products, so what is the difference between the two? The conceptual difference between optical cable and optical braze: The full. Some people are confused with optical fiber and fiber optic cable. Now let's talk about how to differentiate the two products.
