CWDM VS DWDM: A DEEP DIVE INTO WAVELENGTH DIVISION MULTIPLEXING

Wavelength Division Multiplexing (WDM) is a crucial technology used to carry multiple signals over a single optical fiber. There are two primary types of WDM: Coarse Wave Division Multiplexing (CWDM) and Dense Wave Division Multiplexing (DWDM). CWDM uses larger range of wavelengths, typically divided by 20 nanometers. This results in a simpler sys
