Disclosed is a dispersion compensating optical regenerator that provides for enhanced performance of telecommunication systems employing varying soliton signal propagation and dispersion compensation. Allowing the solitons to change in amplitude, width and shape while traversing the dispersion compensating optical regenerator provides for beneficial system performance including improved signal to noise ratio at the receiver, reduced impact of signal interactions, and longer regenerator spacing. The regenerator in accord with the invention comprises a first optical waveguide fiber (4) having positive dispersion, a coupler (6), negative total dispersion fiber (2) and an optical signal polarization controller (8). The regenerator further includes an optical amplifier (10), which is asymmetrically located along the loop fiber (2). The regenerator in accord with the invention combines the filtering features of a NOLM or NALM with the advantageous effects of dispersion compensation. |
