摘要：

We evaluate the effect of refractive-index profile variations on the performance of two-mode fibers used as dispersion compensators in long-distance transmission systems operated near 1550 nm. The comparison of various profiles is carried out for two cases: (i) For a constant operating wavelength away from the LP11-mode cutoff, the step-index fiber is shown to be the best dispersion compensator. (ii) For a constant power confinement in the core (P(core)/P(total)), a matched-cladding, power-law profile with alpha = 6 presents a 20% performance improvement over step-index fibers.
