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…

M-Net use DWDM solution to deliver 500Gbps over a single wavelength

Passive CWDM VS DWDM – Which to choose?

With current industry advancements trend that has equalized costs of transceivers, in a technical battle of CWDM vs DWDM, more advancements are in DWDM. Let’s compare passive CWDM vs DWDM from pure technical application viewpoint: CWDM vs DWDM – Channel Uniformity: As CWDM spectrum for 18 channels spans from 1260nm up to 1620nm compared to DWDM C-band 1530 – 1565…
