ABSTRACT:
An optical receiver is presented, which can receive and evaluate an optical signal (S) containing interference caused by polarization mode dispersion (PMD). The optical receiver has a splitting facility (1.1) which splits the routable optical signal (S) into two electrical signal components (S.sub.-, S.sub.+). The electrical signal components (S.sub.-, S.sub.+) are processed in an equalizing circuit (1.2). A control facility (1.3) controls the splitting facility (1.1) with the aid of a quality signal (Q) produced by the equalizing circuit (1.2).
