Compensating fiber for cumulated chromatic dispersion and chromatic dispersion slope

摘要

A multimode fiber having an index profile such that, for a propagation mode other than the fundamental mode and at a wavelength of 1550 nm, the fiber presents a positive chromatic dispersion greater than or equal to 50 ps/run/km, a positive chromatic dispersion slope and a figure of merit (FOM) greater than or equal to 200 ps/run/dB.
