Cabled SIECOR graded-index fibres show a material dispersion coefficient of (107+or-4) ps/km.nm and a modal dispersion of 200 ps to 300 ps after 1.574 km fibre length, both at lambda =851 nm.enoptical dispersionoptical fibresspectrometersmodal dispersiongrating spectrometermaterial dispersion coefficienttime domain pulse dispersion measurementsgaalas laser diodespectral halfwidth filtergraded index fibre621Experimental method for the separation of material and modal dispersion of optical fibresconference paper
