No, if total internal reflection really occurs at every part i.e. if the angle of incidence is large enough, it should have nothing to do with refractive index or the nature of the cladding material. However, irregularities in the boundary between the core and the cladding fibre results in loss of intensity (attenuation). maj gen thomas suelzerWebDraw a labelled ray diagram to show the refraction of light.
