Copper Fiber Optic
Optical fiber for telecommunications is made up of three parts including the core, cladding & coating. The core is the central part of the fiber which transmits the light. The cladding surrounds the core and keeps the light in the core because it is made of material with a lower index of refraction. The core and cladding are inseparable because they are made up of a single piece of glass silica, treated to create the differences needed in refraction. Finally, a coating generally made of UV protective acrylate is put on a fiber during the draw process to protect it.
