WebCore — The core of the optical fiber carries the vast majority of the optical power. Fibers are designed so the core can be large so it is easier to get light into the fiber. Cladding — … WebThe higher doping concentration of the fiber core (e.g. with germanium), as required for increasing the refractive index difference, may increase scattering losses due to lower optical homogeneity of the fiber core. The same can be caused by irregularities of the core/cladding interface, which are more important for a larger index difference.
