Triangular index fibers have generated considerable interest because of their reported low loss behavior in dispersion shifted (λο = 1.55μm) monomode fibers. Furthermore, the high V-number in such fibers allows core diameters ameters larger than the corresponding step index fibers. However, the sensitivity of several system parameters to the variations in the index structure have not been emphasized. The paper discusses these aspects and outlines a possible mechanism for the observed low loss behavior.
