An inverse multiplexer (also known as an “inverse mux” or “imux”) is a device used in networking and telecommunications that splits a high-speed data stream into several lower-speed data streams. This allows data to be transported over several communication links simultaneously, improving data throughput.

For instance, if you had a data stream operating at 2 Mbps but only had lines capable of transmitting at 1 Mbps, you could use an inverse multiplexer to split the data stream in half and transmit it over two lines concurrently.

Once the split data streams reach their destination, they are recombined into the original high-speed data stream by the inverse multiplexer at the receiving end. This technique is used to maximize the usage of network bandwidth and increase data transmission speed.

The main advantage of inverse multiplexing is that it allows for increased bandwidth by utilizing existing network resources, without the need for expensive high-speed lines or equipment upgrades. However, it requires careful synchronization to ensure that data streams can be correctly recombined at the receiving end.

As of my knowledge cutoff in September 2021, with the rise of high-speed networks and increasing bandwidth of communication lines, the application of inverse multiplexers has been less common. But they still find use in certain situations where these conditions apply.
