DWDM VS CWDM: DEMYSTIFYING WAVELENGTH-DIVISION MULTIPLEXING

In the realm of high-speed networking, effective data transmission is paramount. Optical multiplexing, a key technology enabling this feat, involves transmitting multiple data streams across a single fiber optic cable by assigning each stream a distinct wavelength of light. Two prominent WDM technologies are DWDM and CWDM, each with unique attribut
