At several end stations, a low drift- and low noise conversion of the optical signal into RF signals is needed. In this paper, we present the influence of photodiodes on the phase stability of the optical pulse streams and investigate the drift performance of the photo-detection scheme for the extraction of the RF signal.enNatural Sciences and Mathematics::530: PhysicsTechnology::621: Applied Physics::621.3: Electrical Engineering, Electronic EngineeringConference PaperConference Paper
