Abstract:
A single mode optical waveguide fiber comprising:a segmented core having at least two segments, each of the segments having a radius ri, a refractive index profile and a relative refractive index percent, &Dgr;i%, where i is equal to the number of segments, and a clad layer surrounding and in contact with the core, the clad layer having a refractive index nc; wherein, the ri and &Dgr;i%, and the refractive index profiles are selected to provide: total dispersion at 1530 nm&gE;2ps/nm-km; total dispersion slope <0.1 pS/nm2-km over the wavelength range 1530 nm to 1570 nm; effective area >60 &mgr;m2.
