Dense Wavelength Division Multiplexing (DWDM) is a technology that increases bandwidth by allowing multiple data streams to be transmitted simultaneously over a single optical fiber. It works by using different wavelengths (or colors) of laser light to carry different signals, which are then combined and transmitted together. This method is crucial in the telecom and network management industry as it maximizes the use of existing infrastructure, reduces costs, and enhances data transmission efficiency.
