Abstract (en)

[origin: WO9804941A1] A dispersion compensating single mode optical waveguide fiber designed to change the wavelength window of operation of a link from 1301 nm to 1550 nm. The dispersion compensating waveguide fiber is characterized by a core glass region refractive index profile comprised of at least three segments (2, 4, 6, 8). The segment (2) on the waveguide center has a positive relative refractive index. At least one segment (4, 8), spaced apart from the waveguide centerline has a negative relative refractive index.
