Disclosed is a dispersion compensating waveguide fiber suitable for use in high data rate, high light power telecommunications systems of intermediate length. The refractive index profile of the compensation fiber is segmented. The segment relative refractive indexes and radii are chosen to provide negative total dispersion and negative total dispersion slope over an extended wavelength range. The index profile design is flexible enough to provide compensated links having total dispersion that is positive, negative, or zero, while maintaining appropriate total dispersion slope compensation. In addition, the waveguide fiber of the invention may be cabled or otherwise buffered prior to its use in a communications system.
