Optimized dispersion shifted monomode optical fiber for high data rates

摘要

The invention relates to an optical fiber, with a wavelength lambda0 for which the chromatic dispersion is less than 1500 nm, or greater than 1570 nm, for example close to 1475 nm, and an effective area greater than or equal to 60 m2 . It also has a chromatic dispersion slope between 0,045 and 0,09 ps / nm2 .km for a wavelength of 1550 nm. The present invention applies to the transmission systems in wavelength multiplexing), and makes it possible to limit the non-linear effects, like the four wave mixture, and to limit the use of the dispersion compensating fiber at. / p
