Capacity and Technology Considerations in DAA Backhaul Deployment Strategies (2018)

By Fernando X. Villarruel & Martin Mattingly, Cisco Systems, Inc.

This white paper compares the benefits of several architectural options for the Distributed Access Architecture (DAA) backhaul in the context of bandwidth growth over time. Some of the specific topics covered include the networking and optical implementations needed to address DAA backhaul, routing and TDM framing in hubs and HFC nodes, methodology for estimating needed capacity, concurrency, implementation of direct detect and coherent optics, and cable’s new-found synergies with standard bodies.

After reading this white paper, the cable operator will be able to compare the various architecture options and decision-making process for the deployment and long-term evolution of DAA.
