METHOD AND SYSTEM FOR NON-LINEARITY COMPENSATION IN OPTICAL TRANSMISSION SYSTEMS |
摘要 |
An equalizer (200) for equalization of a signal transmitted via an optical fiber link from a transmitter to a corresponding receiver employs a backpropagation model (300) which comprises one or more sequential segments collectively representing an inverse fiber link. Each sequential segment comprises a linear backpropagation element (304), and a non-linear backpropagation element (306) having an associated compensation bandwidth (312). The equalizer (200) generates a distortion-mitigated signal by computing, for each sequential segment in turn, a first linear compensated signal from a signal input to the segment in accordance with the linear backpropagation element (304), and a non-linear compensated signal from the first linear compensated signal in accordance with the non-linear backpropagation element (306). Computation of the non-linear compensation signal comprises limiting a bandwidth of a compensation signal derived from the first linear compensated signal in accordance with the associated compensation bandwidth (312). |
