ALSO CALLED: Wavelength-division Multiplexing, WDM, Dense Wave Division Multiplexing, Wave Division Multiplexing, Dense Wavelength Division Multiplexing, and D W D M
DEFINITION: Dense wavelength division multiplexing (DWDM) is a technology that puts data from different sources together on an optical fiber, with each signal carried at the same time on its own separate light wavelength. Using DWDM, up to 80 (and theoretically more) separate wavelengths

DWDM DEFINITION (continued): … or channels of data can be multiplexed into a lightstream transmitted on a single optical fiber. Each channel carries a time division multiplexed ( TDM) signal. In a system with each channel carrying 2.5 Gbps (billion bits per second), up to 200 billion bits can be delivered a second by the optical fiber. DWDM is also sometimes called wave division multiplexing (WDM). Since each channel is demultiplexed at the end of the transmission back into …
