Dense Wavelength Division Multiplexing

Dense Wavelength Division Multiplexing (DWDM) is a technology used in fiber optic communication to transmit multiple data signals simultaneously over a single optical fiber. It works by breaking light into various colors (or wavelengths) and sending different data streams on each color. This allows for high-capacity data transmission, making it efficient and cost-effective for Internet and telecommunications networks. By increasing the number of signals that can be sent at once, DWDM greatly enhances bandwidth and is vital for handling the growing demands for data traffic without needing more physical fiber cables.
