Abstract
An optical fiber transmission system includes a series of optical fiber transmission spans and one or more all-optical signal processors. The optical fiber transmission spans are connected to form an optical communication path. Each all-optical signal processor directly connects a corresponding adjacent pair of the spans. Each all-optical signal processor includes an optical wavelength converter having input and output ports and a dispersion adjustment module connected to the input port of the optical wavelength converter of the same processor. The dispersion module is also configured to adjust cumulative dispersions of some received optical pulses to be outside of a range for the cumulative dispersions of corresponding optical pulses in the span directly preceding the same processor.
