Dense wavelength-division multiplexing (DWDM) refers originally to optical signals multiplexed within the 1550 nm band so as to leverage the capabilities (and cost) of EDFAs, which are effective for wavelengths between approximately 1525–1565 nm (), or 1570–1610 nm ().

WDM systems are divided into three different wavelength patterns: normal (WDM), coarse (CWDM) and dense (DWDM). Coarse WDM provides up to 16 channels across multiple transmission windows of silica fibers.

In fiber-optic communications, wavelength-division multiplexing (WDM) is a technology which multiplexes a number of optical carrier signals onto a single optical fiber by using different wavelengths (i.

Dense wavelength-division multiplexing (DWDM) refers originally to optical signals multiplexed within the 1550 nm band so as to leverage the capabilities (and cost) of EDFAs, which are effective for wavelengths between approximately 1525–1565 nm (), or 1570–1610 nm (). FDM (Frequency Division Multiplexing), TDM (Time Division Multiplexing), and WDM (Wavelength Division Multiplexing) are all multiplexing techniques used in telecommunications to transmit multiple signals simultaneously over a single communication channel. If analog signals are multiplexed, it is Analog Multiplexing and if digital signals are multiplexed, that process is Digital Multiplexing.
