Which of the following is a variation of Frequency Division Multiplexing (FDM)?
Open in App
Solution
The correct option is C Wavelength Division Multiplexing (WDM)
The WDM is commonly applied to the optical carrier while FDM is applied on the radio carrier. Since wavelength and frequency are tied together through a simple directly inverse relationship, the two terms actually describe the same concept.
