Time Division Multiplexers are a bit historical but here's an answer.
A number of channels are required to be assembled onto an aggregate. Thirty 64 kbit/s channels could go onto a 2 Mbit/s aggregate for example.
A multiplexer is constructed to a standard such as G.700 series in the ITU-T. In the same box a de-multiplexer is constructed to decode the received 2 Mbit/s.
Also a manufacturer could decide to build a proprietary standard of his own. Timeplex were good at this and made excellent systems with benefits over CCITT later ITU-T standard. Advantages were being able to mix data at different bit rates and also include voice, compressed or not compressed, with or without signalling - if needed. Multiplexers could form meshed networks rather that A-B dumb-bell links and these may need management to sneak in and out of them.
Time Division Multiplexers did what they say, the interleaved the data for each channel or tributary so that it could be received and broken out at the far end. Each channel had its own slot on the frame of the system and came around in a rate which enabled the original bandwidth and clock to be recovered and presented in just the right interface.
They are used in electronics and network devices like phone lines and fiber. A mux takes many signals and turns it into one The reverse of multiplexing is demultiplexing
Broadband refers to telecommunication that provides multiple channels of data over a single communications medium, typically using some form of frequency or wave division multiplexing.
Frequency-division multiplexing, wavelength-division multiplexing, and time-division multiplexing.
Multiplexing is the combination of several signals on one carrier or medium. Demultiplexing is the extraction of each of the original signals. You can't have just one or the other, they are both necessary in the communication process. So the concept of one having an advantage over the other is senseless.
Frequency-division multiplexing and wavelength-division multiplexing
Demultiplexing is to separate 2 or more channels that have been multiplexed. Signals are typically multiplexed or combined onto one higher speed channel to efficiently use the bandwidth.
Multiplexing is the process of combining 2 or more signals together into one multi-component signal with all signals being sent to the same receiver or receivers. Demultiplexing is the process of separating the multiplexed signal into its individual component signals. NOTE: The major distinction between multiplexing and multiple access is that in multiple access the signals are coming from many different sources and are going to many different destinations. Multiplexing is used to describe cases in which there is only one source and one destination for the many individual signals. In an 8086, the address and instruction lines use the same wires, and a pin on the CPU toggles between those two uses. That is one of multiple reasons why the 286 was considerably faster. In addition to a faster clock rate and more dedicated hardware for certain instructions, the 286 had separate address lines and instruction lines. The CPU didn't contain circuitry to switch between the signals and could do addressing and instructions at the same time, and the motherboard was somewhat simpler in that the latches and circuitry to sort the two types of information did not have to be as complex.
