DWDM VS CWDM: A DEEP DIVE INTO WAVELENGTH-DIVISION MULTIPLEXING

In the realm of high-speed data transmission, Wavelength-Division Multiplexing (WDM) emerges as a pivotal technology. This approach enables multiple signals to travel concurrently over a single optical fiber by leveraging distinct wavelengths. Two prominent WDM types, DWDM and CWDM, cater to specific requirements with their distinct attributes. D
