Wavelength division multiplexing or WDM has gained immense traction over the last few years. It has been the preferred choice of technology for transporting massive data in the form of light signals over a fiber cable. By doing so, it maximizes fiber network capacity and avoids excess wiring. Are you intrigued to know more about WDM technology?
