Measurement of normalised frequency in a single-mode optical fibres
It is shown that methods of measuring the normalised frequency in single-mode fibres through observation of mode cut-off wavelengths give erroneous results. This is because the various loss mechanisms which exist in a practical fibre can have an appreciable effect near cut-off.
