Abstract :
We show that the bandwidth of distorted multimode optical fibres excited by quasimonochromatic lasers is equal to the bandwidth of the undistorted fibre divided by the microbending loss measured with l.e.d. sources, to within a numerical factor. This simple result is derived for a slab model, but it may be general.
