In this article
a practical 10GHz frame-clock extraction technology based on unequal coding scheme and high Q value filter is introduced and analyzed.We illustrate its basic principle and propose the theoretical models to simulate the effects of parameters of OTDM (Optical Time Division Multiplexing) signals and high Q value filter.Also
we employ this technology in our practical 40Gbit/s OTDM system
and acquire a series of curves and results related to this unit.Finally
the theoretical and experimental results are compared and discussed.
