摘要:The object of the invention is to provide an optical receiver for an OCDM systemwhich has improved compensating characteristics. The receiver according to the inventioncomprises two filters which are fed by received optical signals and have different passfrequencies. 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 bythe other filter serve as compensation signals that are used to compensate fordisturbances in the desired optical signals passed by the first-mentioned filter. As aresult of the symmetrical design of the receiver with two filters, two optical-to-electricalconverters, and a comparator, optimized compensation is provided and the receiver canbe used in a wide frequency range.
