Fiber Optic are made by different methods, provide transmission of optical radiation on several lengths of waves, have different characteristics and carry out diversiform tasks.
Each fiber consists of a core and a jacket, with different indexes and refractions. The core on which there is a distribution of a light signal, is made from optically more the dense material. In fiber designation through fraction values of diameters of a core and fiber cladding are specified. Fibers differ with diameter of a core and fiber cladding. Fibers differ with diameter of a core and a jacket, and as with a core refractive index profile. In case of manufacture, the modern fiber is used.
