2. Material Scattering Loss



                              Scattering is a general physical process where light are
                              forced to deviate from a straight line by one or more

                              localized non-uniformities in the medium through which

                              they pass.
                              Scattering caused by the interaction of light with density

                              fluctuations within a fibre.

                              Density changes is caused by the contamination  of
                              unwanted materials such as dust and air bubbles causes

                              in optical fibres when optical fibres are manufactured.
                              Often called diffuse reflections.

                              Material Scattering  scatters light out of the core
