Abstract :
Direct timing extraction up to 5.8 GHz in a modified-Manchester-coded time-division multiplexed (TDM) fiber-optic transmission system is reported. The presence of an enhanced discrete timing component surrounded by depressed continuous components in the spectra of the received data is demonstrated experimentally and is supported by theory. The enhanced discrete component is used to injection-lock an electronic oscillator, thus directly generating a large timing signal. The technique is suitable for direct optical injection-locking for timing extraction
