Abstract :
In a paper by E. Jaunart (1990), numerical computations of the main characteristics of single-mode optical fibers (chromatic dispersion, cutoff wavelength, mode-field diameter, etc.) and their measurements on real fibers were compared. The influence of the refractive-index measurement error on the chromatic dispersion calculation has now been investigated, and it is concluded that the fiber refractive-index profile had to be accurately measured in order to obtain a good agreement between computations and measurements. This requirement is quantified, and the discrepancies found previously between computations and measurements are explained.<>
