Single-Mode Optical Fiber Microbend Loss Modeling Using the Finite Difference Beam Propagation Method

Abstract Periodic microbend losses in single-mode optical fibers are modeled here 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 single-mode optical fibers.
