For measuring the frequency response of an optical fibre, a mode scrambler utilising a sinusoidal bend and a new set-up based on the attenuation-comparison method have been proposed. Measurements for multimode step-index fibres have revealed that the long-fibre response can be closely predicted from the short-fibre response, using an appropriate choice for the scrambler parameter.read more

Impulse response prediction based on experimental mode coupling coefficient in a 10-km long graded-index fiber
TL;DR: In this paper, the authors investigated mode coupling coefficients and impulse responses in a multimode graded-index fiber, both experimentally and theoretically, and found that the mode coupling coefficient change due to nylon coating is relatively small.
