Dispersion compensation over 270 km at 10 Gbit/susing an offset-core chirped fibre Bragg grating

Abstract
A 120 mm long fibre Bragg grating, adjustably chirped by an offset-core technique, compensates for dispersion in a 10 Gbit/s optical communication system operating at 1054 µm over 270 km of non-dispersion-shifted fibre. Simultaneous compensation of fibre dispersion and source chirp in a directly modulated system is also described.
