{Optical fibres characterised both by the number of different refractive index layers around the central core segment, i.e. around the innermost high index core layer, and their relative refractive index difference} [2013-01]
NOTE

  • A layer is characterised by an abrupt change in refractive index gradient, e.g. by the layer having a maximum or minimum or the layer being between two points of inflexion, such that a graded boundary as in a trapezoidal core is not counted as a separate layer. 2. The innermost high index core layer is the first layer starting from the central core after which the refractive index decreases. 3. + and - refer respectively to the relative refractive index difference increase/decrease of adjacent layers starting from the innermost highest index core layer and continuing in a radially outward direction
