CWDM VS DWDM: UNDERSTANDING WAVELENGTH DIVISION MULTIPLEXING TECHNIQUES

Wavelength Division Multiplexing (WDM) techniques is a crucial component in optical communications, enabling the transmission of multiple signals over a single fiber optic cable. There are two primary types of WDM: Coarse Wave Division Multiplexing (CWDM) and Dense Wave Division Multiplexing (DWDM). CWDM utilizes a wider range of wavelengths, com
