GS7000 Fiber Deep Node w/Remote PHY

GS7000 Strand Mount Housing
Part Number: GS7000 Fiber Deep Node

Consumer bandwidth demand continues to grow at a rapid rate every year. As a result, cable operators with devices based on DOCSIS need to prepare their networks for the future. They need to plan for reduced service group sizes and ultimately for double or quadruple (or greater) bandwidth speeds. The Cisco® GS7000 1218-MHz 4-Port Fiber Deep Node coupled with the Cisco Smart PHY Model 120 1x2 RPD (Remote PHY device) module enables them to implement these plans.
An extension of the modular headend architecture, MHAv2 splits CMTS functions so that 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 QAM and 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 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.
