Optical fiber with large effective core area and high chromatic dispersion

摘要

An optical fiber is disclosed having, at a wavelength of 1 550 nm, an effective core area not less than 100 mum2, a chromatic dispersion from 14 ps/(nm.km) to 21 ps/(nm.km) and good resistance to microcurvatures. The specifications of the fiber limit non-linear effects and provide sufficient transmitted power for transmission systems. A fiber optic transmission system using fiber of the above kind as line fiber is also disclosed.
