Abstract

The shape of the impulse reponse of a step index, multimode fiber of circular cross section with material limited by Rayleigh scattering only is nearly invariant with fiber length L, unless L is so large that the signal has suffered an enormous scattering loss. The percent fraction of pulse energy responsible for distortion by scattering ≃8.63 (1 − n²_CL/n²_CO) W_dB, where W_dB is the associated energy reduction in decibels due to scattering from the core, and n_CL, n_CO are the refractive indexes of cladding and core, respectively. W_dB is nearly equal to length in kilometers for highly transparent material.
