DWDM VS CWDM: UNDERSTANDING WAVELENGTH DIVISION MULTIPLEXING

Wavelength Division Multiplexing (WDM) is a process used to transmit multiple signals over a single fiber optic cable. By splitting the available bandwidth into separate wavelengths, WDM allows for high-speed data transmission. There are two primary types of WDM: Dense Wavelength Division Multiplexing (DWDM) and Coarse Wavelength Division Multiplex
