Abstract
The present invention relates to a method of generating a clock signal of exact phase from an optical input signal that is divided up optically into two channels, one for data extraction to generate an electrical data signal and one for clock extraction to generate an electrical first clock signal, so that the phase position of the first clock signal is corrected by comparison with the phase position of the data signal so that the phase position of the resulting clock signal formed after this correction is similar to the phase position of the data signal, and also a digital optical receiver therefor.
