The 1830 VWM constitutes the backbone of the wireless fronthaul solution by establishing an end-to-end transport line between RRHs and the centralized BBUs.

At the cell site: The 1830 VWM TLU provides the colorization of the black and white signals and the 1830 VWM PMU provides the add-drop functionality. The 1830 VWM ITP is an integrated TLU and PMU device that provides wavelength translation and passive wavelength division multiplexing capabilities.

At the central office: The 1830 VWM TLUs and 1830 VWM PMUs are connected to an 1830 VWM OSU to form the central management hub for OSC signals transported using the out-of-band channels from the peripheries. The 1830 VWM OSU provides the management interface to the NFM-P.
