An optical fiber is disclosed for compensating the chromatic dispersion of on optical fiber with positive chromatic dispersion advantageously has, at a wavelength of 1 550 nm, a chromatic dispersion less than −40 ps/(nm.km), or even less than −50 ps/(nm.km), a ratio between the chromatic dispersion and the chromatic dispersion slope from 50 nm to 230 nm, an effective surfaced area greater than 12 μm2 and curvature losses less than or equal to 0.05 dB. It is used for in-line compensation of cumulative chromatic dispersion in a line fiber with positive chromatic dispersion. Also disclosed is a fiber optic transmission system using a fiber of the above kind to compensate cumulative chromatic dispersion in the line fiber.
A dispersion compensating optical fiber having at a wavelength of 1 550 nm a chromatic dispersion less than or equal to −40 ps/nm.km, a negative chromatic dispersion slope, a ratio of chromatic dispersion to chromatic dispersion slope from 50 nm, to 230 nm, an effective surface area greater than or equal to 12 μm2 and curvature losses less than or equal to 0.05 dB for 100 turns wound with a radius of 30 mm.
