Abstract
The normalized propagation constants and delay parameters of near parabolic index fibres are obtained by first order perturbation theory. Departures from the parabolic variation in the form of gaussian dip or bump, periodic changes and polynomial functions are combined in a single term allowing the generalization of existing results. The relevant parameters for each of these special cases are also obtained separately in a closed form.
