The initial transient behaviour of the clock is measured when a long sequence of zero bits is present in the injected signal. The dephasing of the extracted clock due to inherent noise and the lock-up time are studied. The main goal is an estimate for the maximum tolerable zero bit sequence.enclocksdistributed feedback lasersintegrated opticslaser feedbacklaser frequency stabilitymultiplexing equipmentoptical communication equipmentoptical fibre communicationsynchronisationtime division multiplexingstabilityall-optically extracted clockself pulsating dfb-laserperformanceinitial transient behaviourinjected signaldephasinginherent noiselock-up timemaximum tolerable zero bit sequence18 GHz621Investigations on the stability of an all-optically extracted clock at 18 GHz using a selfpulsating DFB-laserconference paper
