Abstract

We have defined new Equivalent Step-Index parameters for single-mode fibers having a graded core profile and/or a central index dip. These parameters are obtained from the actual index profile through simple analytical expressions with a straightforward physical interpretation. As compared to previous ESI theories, they allow a better accuracy in predicting the transmission characteristics of the fibers. In particular, the use of these ESI parameters with the usual models for calculating the chromatic dispersion in single mode fibers proves very efficient : the accuracy in predicting the zero dispersion wavelength is better than 2 nm for nearly step index fibers designed for the 1.3 μm window, and it remains better than 15 nm for triangular core profile fibers designed for the 1.55 μm window.
