How Wavelength Division Multiplexing (WDM) Works
Each data stream is first converted into pulses of laser light, with each stream assigned a unique, precise wavelength, comparable to assigning a specific radio frequency to each radio station.

Understanding Wavelength Division Multiplexing (WDM)
Since wavelength and frequency have an inverse relationship (shorter wavelength means higher frequency), the WDM and FDM both contains the same technology in them.

Wavelength-division multiplexing
External wavelengths in the 1,550 nm most likely need to be translated, as they almost certainly do not have the required frequency stability tolerances nor the optical power necessary for the system''s EDFA.
