Typical bre connections are affected by various limitations which have a major
impact on transmission behaviour. These limitations cause backscattering and
additional attenuation. They include the various splicing connections and also
the direct limitations of the bres themselves from severe bending, fractures
or cracks. Each of the limitations mentioned has its own typical reection
characteristic and can therefore be detected and analysed directly in the OTDR
measurement.
