DWDM (Dense Wavelength Division Multiplexing) serves the same purpose as CWDM. However, DWDM can utilize 80 wavelengths—40 in the C-band and 40 in the L-band. Consequently, DWDM enables higher-speed communication over a single fiber.
As iFiber, we offer all the necessary SFP, SFP+, MUX, and DEMUX solutions for DWDM through the SmartOptics brand, for which we serve as a distributor.
