CWDM VS DWDM: A DEEP DIVE INTO WAVELENGTH DIVISION MULTIPLEXING

CWDM and DWDM are methods within the broader field of wavelength division multiplexing (WDM). Both techniques utilize different frequencies of light to transmit data over a single fiber optic cable, effectively increasing bandwidth and transmission capacity. CWDM operates with coarser spacing between wavelengths, typically 20 nanometers, making it
