Abstract :
Novel waveform monitoring technique for 160 Gbit/s OTDM signal using an asynchronous EAM prescaler is proposed. This waveform monitor can detect waveform distortion caused by residual dispersion, PMD and OSNR degradation separately. And the feasibility of the monitor was examined by experiments and numerical estimations.
