✦ Synopsis
Periodic microbend losses in single-mode optical fibers are modeled here Ž . by using the finite difference beam propagation method FD-BPM . To reduce computational demands, the sinusoidal microbending deformation is approximated as a series of constant curvature bends of alternating sign. The spectral sensitivity is determined by performing calculations over the wavelength range 1170᎐1450 nm. Results obtained display the distinct attenuation bands which are typical of this form of induced loss. Comparison with experimental results taken from a previous study suggests that the FD-BPM provides a useful strategy for predicting the spectral attenuation in singlemode optical fibers.
