Basic structure of optical fiber
The general structure of optical fibers includes three parts: Fiber core, Cladding, and Jacket.
Both the core and cladding are made of glass of different refractive indices. The innermost part is the core, and the second layer on the top of the core is the cladding of an optical fiber. They have different refractive indices, and the refractive index of the core is always greater than the index of the cladding. This index difference causes total internal reflection to occur at the index boundary along the length of the fiber.
