In the last decade Optical Time Division Multiplexed (OTDM) systems have attracted considerable interest, as an alternative to the existing commercially deployed Wavelength Division Multiplexed (WDM) systems. In this presentation, first the basic point-to-point bit interleaved OTDM system will be explained, with special focus on the transmitter and the receiver functionalities, demultiplexing and clock extraction. Some reported results are highlighted. In order to expand the system to include a number of nodes, channel identification is required, and a novel technique will be introduced. A simple network configuration is presented, exemplifying advantages and drawbacks of bit interleaved OTDM systems. Finally, a short introduction to reported results on packet based OTDM systems will be presented.
