With Dense Wave Division Multiplexing (DWDM), data can be sent along multiple wave- lengths or colors within a fiber. The new metro DWDM gear goes one step more by using a variety of multiplexing techniques to further split the wavelength among customers and support a mix of data and voice traffic.
