ABSTRACT:
An electrical equalizing facility for an electric input signal (S) which was derived from an optical signal (L) transmitted over an optical fiber and which is distorted due to interference in the optical signal (L) as a result of, e.g., polarization mode dispersion (PMD) comprises a number (n>1) of parallel-connected, different, variable electronic equalizers (E.sub.1, . . . , E.sub.i, . . . E.sub.i,m), which are supplied with the electric input signal (S), and a control unit (3) for selecting the electric output signal (S.sub.i) of the respective best equalizing electronic equalizer (E.sub.i) and for controlling the equalization parameters (E.sub.i,1, . . . , E.sub.i,m) of this equalizer in such a way that the quality (Q) of its equalized signal (S.sub.i) is optimized. This makes it possible to select the equalizer currently operating satisfactorily.
