WebRayleigh scattering is the dominant reason for propagation losses in optical glass fibers (particularly single-mode fibers) at shorter wavelengths, e.g. in the visible and ultraviolet spectral range. Even for perfect glass quality, scattering occurs at the density fluctuations in the glass, which are to some extent unavoidable.
