Abstract
We propose a self-clocking method based on in-band clock pilot insertion at the transmission data signal. The method can achieve clock recovery without the need for an ultrafast phase comparator and a phase-locked loop in the receiver. We demonstrate fast synchronization, low timing jitter, and a highly stable recovered clock from a optical time-division multiplexing data signal after a fiber transmission. The recovered clock shows no patterning effect with a clock dynamic range of for error-free operation of demultiplexing with a power penalty of .
