This paper introduces the principle of using non-equal amplitude principle to extract the frame clock components. The theoretical model and experimental block diagram of using 10GHz frame clock in the 40Gbit / s optical time division multiplexing (OTDM) system are described. The OTDM light Signal parameters and clock extraction unit parameters on the system, and gives the theoretical analysis of results; analysis of the actual implementation of the clock extraction unit and the experimental results; and the theoretical results and experimental results were analyzed and compared.
