Abstract: The optical time-division multiplexing (OTDM) incorporates and expands the techniques of time division multiplexing (TDM) in the optical domain. In the OTDM, building of the optical data streams is done by multiplexing a variety of optical streams with a lower bit rate. Researchers have focused on approaches based on Wavelength Division Multiplexed (WDM) in which the wavelength of the light is utilized as the degree of freedom to provide a route to the signals using the optical selection or filtering stages. An extensive investigation has been done on the use of the wavelength not only for closed user broadcast networks but also for the single as well as multihopping transport networks. We hereby present a summary of the recent works on the optical time-division multiplexing (OTDM) and de-multiplexing. We define the design considerations that emphasis on factors that restrict the system performance. These design considerations include multiplexed channel cross-talking that that affect system architecture.
