Passive CWDM vs DWDM: What’s the Difference?

WDM (Wavelength Division Multiplexing) is a commonly used technology in optical communications. It is often deployed to join multiple wavelengths onto a single fiber. In the WDM system, there are two main types: Coarse Wavelength Division Multiplexing (CWDM) and Dense Wavelength Division Multiplexing (DWDM). Both CWDM and DWDM are available as active or passive systems. This article will focus on discussing the difference between…
