Title: OPTICAL FIBRE WITH CHROMATIC DISPERSION COMPENSATION
Abstract:
The invention concerns an optical fibre for compensating the chromatic dispersion of an optical fibre with positive chromatic dispersion. The inventive fibre has advantageously for a wavelength of 1500 nm a chromatic dispersion less than 40 ps/(nm.km), a ratio between the chromatic dispersion and the chromatic dispersion slope ranging between 50 and 230 nm, and an effective area greater than 12 νm2, and bend losses not more than 0.05 dB. It enables to compensate chromatic dispersion accumulated in a fibre with positive chromatic dispersion. The invention also concerns an optical fibre transmission system using such a fibre to compensate chromatic dispersion accumulated in the line fibre.
