The object of the invention is to provide an optical receiver for an OCDM system which has improved compensating characteristics. The receiver according to the invention comprises two filters which are fed by received optical signals and have different pass frequencies. One of the filters is matched to the optical signals to be received. The other filter is not matched to the optical signals to be received. The optical signals passed by the other filter serve as compensation signals that are used to compensate for disturbances in the desired optical signals passed by the first-mentioned filter. As a result of the symmetrical design of the receiver with two filters, two optical-to-electrical converters, and a comparator, optimized compensation is provided and the receiver can be used in a wide frequency range.
