✦ Synopsis

Propagation of axisymmetric normal longitudinal waves in an in"nite optical "ber with a thin boundary layer is considered. Properties of these waves (pro"les, dispersion curves) are obtained by both numerical and analytical methods. Coincidence of the results from numerical and analytical methods is found. It is shown that one or two waves can propagate along the "ber depending on properties of the boundary layer, which corresponds to one or two branches of dispersion curve. An expression for calculation of cut-o! frequency for second wave is obtained.
