ABSTRACT:
A receiver for an optical signal is described. The receiver comprises a decision feedback equalizer (DFE), wherein a distorted input signal (DIS) being derived from the optical signal, as well as a first threshold signal (Th1) and/or a first coefficient (Coeff1) are provided to the decision feedback equalizer (DFE), and wherein an error signal (ES1) is provided by the decision feedback equalizer (DFE). The receiver comprises a control unit (CU), wherein the error signal (ES1) is provided to the control unit (CU), and wherein the first threshold signal (Th1) and/or the first coefficient (Coeff1) are adapted by the control unit (CU). The receiver comprises an eye monitor (EM) for optimizing the adapted first threshold signal (Th1) and/or the adapted first coefficient (Coeff1), wherein the distorted input signal (DIS) is provided to the eye monitor (EM).
