Dispersion slope compensating optical waveguide fiber

A telecommunications link comprising:

• a transmitter for generating light signals;
• a receiver for receiving the light signals;
• at least two lengths of optical waveguide fiber optically joined in series to form a link length, the link length having a first end optically coupled to said transmitter and a second end optically coupled to said receiver to transport the light signals therebetween;
• wherein,
• a first one of said at least two lengths of optical fiber has a positive total dispersion and a positive total dispersion slope, and a second one of said at least two lengths has a negative total dispersion and negative total dispersion slope, wherein,
• the first and second lengths are selected such that said link has a total dispersion of magnitude less than 10 ps/nm-km, and a total dispersion slope of magnitude less than 0.01 ps/nm2-km, over a pre-selected wavelength range.
