Abstract:
A dispersion compensating optical regenerator for use in a waveguide fiber telecommunications system comprising:a first optical waveguide fiber having a positive total dispersion and a first length; a second optical waveguide fiber for compensating dispersion of said first optical waveguide fiber, said second optical waveguide fiber having a second length and a negative total dispersion and being incorporated into a loop mirror, wherein said second optical waveguide fiber carries counter-propagating varying-soliton signals in the loop mirror; phase shifting means incorporated in the loop mirror to produce a phase shift between the counter-propagating varying-soliton signals in the loop mirror, the phase shift produced being sufficient to cause varying-soliton signals to be coupled out of the loop mirror; wherein, the respective first and second lengths multiplied by the respective positive and negative total dispersions of the optical waveguide fibers provide respective dispersion products that add algebraically to provide an average total dispersion over the total length of optical waveguide fiber of the optical regenerator and said dispersion products are chosen to provide an average total dispersion of said dispersion compensating optical regenerator that is within a pre-selected range.
