Abstract
Disclosed is a dispersion shifted optical waveguide fiber having low but non-zero dispersion over an extended wavelength window that includes wavelengths, from 1470 nm to 1625 nm. Waveguide fiber core refractive index profiles exhibit the desired dispersion performance while maintaining resistance to pin array and lateral load bending at least equivalent to standard waveguide fiber. Attenuation over the operating wavelength range is low and zero dispersion wavelength is typically less than 1450 nm.
