Differences Between Optical Fiber and Fiber Optic Cable

Optical fiber is a thin and flexible medium for transmitting light beams. Before use, most optical fibers must be covered by several protective layers, and the cabled form with these layers is referred to as a fiber optic cable.

Therefore, optical fibers constitute the core part of fiber optic cables. With the addition of components and associated protective layers, optical fibers form complete fiber optic cables.

The protective structure on the outer layer of optical fibers serves to prevent environmental damage to the fibers. A fiber optic cable comprises the optical fiber, a buffer layer, and an outer covering.

Similar to coaxial cables, optical fibers lack a mesh shielding layer. The central part consists of a glass core through which light propagates.

Optical fibers are often bundled and encased in an outer shell for protection.

The fiber core is typically a small cross-sectional double-layered concentric cylinder made of quartz glass, known for its brittle and breakable nature, hence requiring an additional protective layer. This is where their distinction lies.
