    Optical Add Drop Multiplexers act as on and off ramps for a single mode DWDM by adding bands of channels to a WDM signal—or removing and rerouting individual wavelengths to specific destinations as the remaining signals continue down the trunk.

    This technology is often used to provide dedicated channels to businesses or small clusters of subscribers.
