WebApr 20, 2024 · DWDM networks are optical networks that use the principle of wavelength division multiplexing (WDM), which allows one optical fiber to transmit several optical carriers, each at a different wavelength. The advantage is that the transmission at each wavelength can take place with a different transmission rate and modulation.
