TRANSMISSION OF SOLITONS ON ALTERNATE SIGN DISPERSION OPTICAL FIBRES WITH PHASE CONJUGATION

摘要

An optical transmission system comprising optical fibres having dispersion of alternate sign greater, in absolute value, than 1 ps / (nm km) arranged in an optical path in accordance with a dispersion map appropriate for the transmission of DM solitons at a wavelength λc. The system comprises a transmission station and a receiver station connected to the said optical path. The transmission station launches on the said optical path at least a first optical pulse RZ. At least one phase conjugation device is located along the said optical path to invert the spectrum of at least the said first pulse. This phase conjugation device is located in a chirp cancellation portion of the said optical path which includes a point at which the chirp of a DM soliton of wavelength λc is cancelled out.
