Abstract
The invention relates to a dispersion shifted monomode optical fiber which, in the wavelength range 1400 nm to 1650 nm, presents both a chromatic dispersion maximum and a chromatic dispersion slope of absolute value less than 0.05 ps/nm ·km. Advantageously, the maximum in the wavelength wave 1400 nm to 1650 nm is a single maximum. The fiber also presents dispersion having a slope of absolute value less than 0.03 ps/nm ·km in the wavelength range 1530 nm to 1580 nm. The fiber of the invention is particularly suitable for wavelength division multiplexed transmission systems.
