Abstract

A simple analytic formula for the microbending loss in monomode fibres of arbitrary refractive-index profile is presented. This loss essentially depends on the spot size of the fundamental fibre mode only. Therefore W-fibres, for example, are as sensitive to microbending as conventional cladded-core fibres.
