Abstract
Shuttle pulse measurements in a multimode optical fiber were used to determine pulse dispersion, at λ = 0.9-μm wavelength, in eight increments from 148-m to a 2516-m extrapolated length. There was relatively little mode mixing in this low loss fiber (minimum loss = 1.7 dB/km at λ = 1.04 μm), and the observed pulse width was primarily due to the grading of the refractive-index profile.
