| CWDM Vs DWDM | Coarse Wavelength Division Multiplexing Vs |
|---|---|
CWDM is cost-effective, suitable for short to medium distances, and simpler to deploy, making it ideal for metro and access networks. DWDM provides higher capacity and is suitable for long-distance, high-capacity applications, but at a higher cost and complexity. | |
