Disclosed is a single mode optical waveguide fiber having a segmented core. The relative indexes, the refractive index profiles and the radii of the segments are chosen to provide waveguide fiber properties advantageously use d in severe environments, such as, undersea cables. The segmented core wavegui de fiber has a negative total dispersion over the operating window of about 153 0 nm to 1570 nm, which serves to eliminate soliton formation. The key properti es of dispersion zero, cut off wavelength, attenuation, and bend resistance fal l within desired ranges. The waveguide also features a low polarization mode dispersion.
