Whenever the transmission capacity of the medium linking two device is greater than the transmission needs of the device, the link can be shared.. As a large water pipe can carry water to several separate house at once.. Multiplexing refer to the combination of information streams from multiple sources for transmission over a shared medium. Multiplexor is a mechanism that implements the concept. . Demultiplexing. refer to the separation of a combination back into separate information streams. optical telecommunication networks. Outline.

Performance.. Introduction. Under the simplest conditions, a medium can carry only one signal at any moment in time. For multiple signals to share one medium, the medium must somehow be divided, giving each signal a portion of the total bandwidth.. HSC PDHPE – CQ2 DP1.
