Abstract:
A dispersion compensating optical waveguide fiber comprising:a core region surrounded by and in contact with a clad layer, the core region and the clad layer having respective refractive index profiles; wherein, the respective refractive index profiles are selected to provide an optical waveguide fiber having, at a wavelength of 1550 nm, a total dispersion in a range from âˆ’12 ps/nm-km to âˆ’35 ps/nm-km, a total dispersion slope in a range from âˆ’0.04 ps/nm2-km to âˆ’0.11 ps/nm2-km, and attenuation at 1550 nm of less than or equal to 0.25 dB/km.
