Description
The Advanced RPD (ARPD) is a next-generation headend product that offers greater demodulator density in a more compact chassis than the currently fielded RPD-2000 product. The ARPD is a modular 1 RU product that supports the inclusion of up to six removable (hot-swappable) demodulator modules (ADM-4000 modules). The ARPD performs the same functions as the RPD-2000 product, but offers a larger number of upstream demodulators in a smaller physical package. In addition to saving rack space, the ARPD easily and efficiently allows multiple upstream demodulators to be placed in each upstream path.
