Webdivision multiplexing (OTDM), such that each input channel transmits its data in an assigned time slot. This assignment is performed by a fast multiplex switch (mux). Functionally, optical TDM (OTDM) is identical to electronic TDM. The only difference is that multiplexing and demultiplexing operations are performed entirely optically at high ... WebIn conclusion, the TDM-PON and the WDM-PON have advantages and disadvantage in a complimentary way. The advantages of the former are disadvantages of the latter and vice versa. As a result, to combine the TDM and WDM technologies into PON, i.e. WDM/TDM-PON is quite valuable because it allows multiple users to share one WDM wavelength’s …
