Networking - Interview Questions and Answers

WDM is conceptually the same as FDM, except that the multiplexing and demultiplexing involve light signals transmitted through fiber optics channel.

TDM is a digital process that can be applied when the data rate capacity of the transmission medium is greater than the data rate required by the sending and receiving devices.

In STDM, the multiplexer allocates exactly the same time slot to each device at all times, whether or not a device has anything to transmit.
