What Is an Optical Fiber Cable? Core Definition
An optical fiber cable (often abbreviated as fiber optic cable) is a type of communication cable specifically engineered for transmitting optical signals. At its core, it consists of a certain number of optical fibers (the light-transmitting carriers) arranged into a cable core in a specific manner. This cable core is then wrapped with a protective sheath, and in some cases, an additional outer jacket, to form a complete, durable transmission line.
To put it simply: An optical fiber cable is a “packaged” product made by processing optical fibers through specialized manufacturing processes. While optical fiber itself is the thin, fragile glass or plastic fiber that carries light signals, the optical fiber cable integrates these fibers with protective and reinforcing components to make them suitable for real-world use in various environments.
