Dense Wavelength Division Multiplexing 100G DWDM Mux Demux ABS box type

Modulelink Dense wavelength division multiplexing (DWDM) is a technology that puts together -- multiplexes -- data signals from different sources so they can share a single optical fiber pair while maintaining complete separation of the data streams. Each signal is carried on a separate light wavelength; the dense part of DWDM refers to the fact that more than 80 separate wavelengths, each about 0.8 of a nanometer (nm) wide, can share a single optical fiber.
