Abstract
Optoelectrical conversion of the received optical service signal (OSS), bandpass filtering and subsequent squaring produce a spectral line at the clock frequency (f). This clock line (TL) is selected by means of narrowband filtering and rectified. The service signal voltage (V) obtained in this manner is used to switch on a Raman pump laser ().
