Cladding

Cladding is a material layer which surrounds the core of a fiber and is used to help propagate light through the fiber. The cladding layer is usually made of glass, plastic, or quartz and is slightly less transparent than the core material. This allows the cladding to reflect a portion of the light back into the core of the fiber. The purpose of cladding is to contain the light within the core of the fiber. Light travels through the core of the fiber due to the fact that it has a lower refractive index than the cladding. The light is then able to be reflected off of the cladding back into the core instead of being scattered in other directions. This allows the light to travel further down the fiber with minimal loss. Cladding is an important part of fiber optics technology and is used in a variety of applications. It can be used to create fiber optic cables for data transmission, or to create fiber lasers for medical applications. The cladding layer also helps to protect the core from environmental elements that can cause damage. Cladding is an important component in the design of fiber optics and has many applications. It helps to contain the light within the core of the fiber and improves the efficiency of the fiber. The cladding layer also helps to protect the core from environmental elements that can cause damage. By using cladding, fiber optics can be used in a variety of applications, such as data transmission, medical applications, and more.
