As the newest step in the continuing evolution towards an all headend, Distributed Access Architecture (DAA) extends the digital portion of the headend/hub domain out to the fiber optic node and places the digital/RF interface at the optical/coax boundary. This strategic move offers many benefits, including increased bandwidth capacity, improved fiber efficiencies (wavelengths and distance), simplified plant operations with digital optics, decreased loads on facility space and power systems, and directional alignment with FTTx systems of the future.
Implementing DAA involves installing Remote PHY Devices (RPD’s) in ARRIS form fitting nodes, supported by a Gen 2 E6000 chassis acting as an electronic Core (eCore) Managing this deployment across many headends and dozens or hundreds of nodes is a time-consuming, potentially service-affecting activity that must be approached with careful planning and execution.
With over 20 years of experience, ARRIS Global Services can help cable operators plan, design, implement and operate the changes required in their network to achieve a flexible, sustainable network. ARRIS’s skilled Project Managers, Deployment Engineers and Technicians can manage and execute the transition to DAA, allowing cable operator personnel to stay focused on business as usual.
