Abstract
It has been shown by a number of authors /1-3/ that for a practical range of V values, the field profile of the fundamental mode can be closely approximated by a Gaussian function more or less independent of the exact shape of the fiber’s refractive-index profile. This property has naturally led to the idea of replacing (for calculations) the complex profiles typical to MCVD fibers, by equivalent-step-index (ESI) models /2–4/ that yield reasonably accurate estimates of parameters such as constant bend, transition (microbend), and coupling losses /3/. The prediction of dispersion behaviour from ESI parameters is presently somewhat uncertain /5/.
