Abstract :
35fs timing-jitter clock recovery based on EAM-MZM double-loop with ability of simultaneous demultiplexing is proposed to enable a 640Gbit/s-400km OTDM transmission system with power penalty of 4dB. Results show significant performance improvement compared with MZM-OEO based clock recovery in system.
