CWDM VS DWDM: A DEEP DIVE INTO WAVELENGTH DIVISION MULTIPLEXING

Wavelength Division Multiplexing (WDM) is a crucial technology used to send 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 more extensive range of wavelengths, typically spaced by 20 nanometers. This produces a simpler
