DWDM
Dense Wavelength Divisonal Multiplexing
DWDM is the techonology used in optical amplifiers, such as EDFA
DWDM
Dense wavelength division multiplexing (Wikipedia). Basically, a scheme for carrying oodles of channels via optical fibers; one fiber carries many different "colors" (wavelengths) of infrared light, and each "color" is a separate communications channel. See Wikipedia

DWDM -- See the Wikipedia article. Not found in homes, and won't be, for some time, most likely.
