Abstract

The cores of modern optical fibers are constructed of multiple layers having differing refractive index. By consistently building each layer separately can be modeled random profile of refractive index, which best meets, the stated requirements to the fiber. For the calculation of refractive index ni of each layer of the fiber can be used so-called formula Selmayer valid for binary silicon glass. The practical calculations can be a particular problem. he article provides some examples of calculation of the refractive index of single-layer optical fiber built on silica doped with germanium dioxide diboron trioxide, phosphorous pentoxide and fluorine
