In fiber optics, **cladding** refers to the outer optical layer that surrounds the central core of an optical fiber. The core is the light-carrying part of the fiber, typically made of glass or plastic, and it is designed to transmit light signals. The cladding, on the other hand, is made from a different type of glass or plastic material that has a lower refractive index than the core.
