Abstract
A method for transmitting an additional data signal and a useful data signal, via optical connections, in an optical network, wherein the additional data signal is transmitted on the same channel as the useful data channel and converted into code sequences which are, in turn, superimposed on the useful data signal with a small amplitude. At the reception end, the additional data signal is recovered by cross-correlation.
