Abstract: It is shown that the widely used method for calculating the SBS threshold in optical fibres yields erroneous results in a number of practically important cases. In particular, not all acoustic-antiwaveguide optical fibres demonstrate an increase in the SBS threshold. For the SBS threshold to increase, it is necessary to provide fast disruption of the acoustic wavefront due to refraction.
