The Cisco Remote PHY Model 220 2×2 Remote Phy Device (RPD) module for the GS7000 BAU node enables customers to prepare their networks for the future with higher bandwidth per subscriber.
An extension of the Modular Headend Architecture (MHA), MHAv2 splits Cable Modem Termination System (CMTS) functions so that Converged Cable Access Platform (CCAP) core and physical-layer functions can run separately, in different locations. CCAP core routing can run out of larger hubs (or even cloud CMTS instances in a data center), while Quadrature Amplitude Modulation (QAM) and Orthogonal Frequency Division Multiplexing (ODFM) modulation gets pushed out to Remote PHY Devices (RPDs) located nearer to subscribers.
Remote PHY is the product of cable operators asking the industry to help them overcome the limitations of analog fiber and break through the Hybrid-Fiber Coaxial (HFC) bottleneck. In its most basic form, Remote PHY unlocks major bandwidth increases in existing access networks. But it also enables “fiber-deep” architectures that push digital fiber out much closer to homes. Ultimately, Remote PHY helps cable operators deliver capacity and Gigabit service tiers on par with any pure-fiber competitor, at a fraction of the cost of ripping and replacing the existing HFC plant.
