    en.wikipedia.org/wiki/Multi-mode_optical_fiber

    Multi-mode fibers are described by their core and cladding diameters. Thus, 62.5/125 μm multi-mode fiber has a core size of 62.5 micrometres (μm) and a cladding diameter of 125 μm. The transition between the core and cladding can be sharp, which is called a step-index profile, or a gradual transition, which is called a graded-index profile.

    One purpose of doping is to raise the refractive index (e.g. with germanium dioxide (GeO 2) or aluminium oxide (Al 2 O 3)) or to lower it (e.g. with fluorine or boron trioxide (B 2 O 3)). Doping is also possible with laser-active ions (for example, rare-earth-doped fibers) in order to obtain active fibers to be used, for example, in fiber ...
