Measuring Distributed Mode Scattering in Long, Few-Moded Fibers [PDF]
We present measurements of higher-order modes in lengths of few-moded fibers up to 0.5 km long using Spatially and Spectrally resolved (S2) imaging. Both discrete scattering events and mode-mixing due to distributed scattering are measured.
