    Wavelength division multiplexing WDM is similar to frequency-division multiplexing (FDM) but referencing the wavelength of light to the frequency of light. WDM is done in the IR portion of the electromagnetic spectrum instead of taking place at radio frequencies (RF). The lines direct their transmission streams to a multiplexer (MUX), which combines them into a single. In telecommunications, multiplexing is a fundamental technique that allows multiple data streams to travel over a single medium, like a fiber optic cable.
