Fiber optic cable and optical fiber cable are the same; both terms refer to a cable assembly that contains one or more optical fibers for transmitting light.

A fiber optic cable (also called an optical fiber cable) is an assembly that houses one or more optical fibers, which are thin strands of glass or plastic that transmit light signals over long distances with minimal loss and immunity to electromagnetic interference . The optical fibers themselves are the core technology, consisting of a core and cladding designed for total internal reflection, allowing light to travel efficiently . The cable is the protective infrastructure around the fibers. It includes buffer coatings, protective sheaths, and sometimes additional layers to shield the fibers from environmental factors such as moisture, temperature changes, and physical stress . This assembly ensures durability, flexibility, and reliability in various applications, from indoor networking to long-distance telecommunications . In essence, the optical fiber is the light-carrying element, while the fiber optic cable is the complete product that packages and protects these fibers for practical use. The terms are often used interchangeably in industry contexts, but technically, the cable refers to the full protective assembly, whereas the fiber refers to the core light-transmitting medium . Fiber optic cables come in different types, such as loose-tube, tight-buffered, and ribbon cables, depending on the installation environment and application, but all serve the same fundamental purpose of safely transmitting optical signals .
