DAA Out in the Field: The Real Story
Wednesday, October 14, 2020: 1:00 PM - 2:00 PM EDT
The tireless evolution of the access network toward smaller and smaller service groups, combined with the migration from analog to digital optics, is a familiar topic for seasoned Expo attendees. This three-part deep dive on the state of Distributed Access Architectures (DAA), led by engineering DAA pioneers from Comcast and Cisco, tells the story of what’s really going on in the field. Steve Sigman opens the workshop with a review of how and why the DAA migration is necessary and beneficial, as well as how Remote PHY can be implemented for different use cases, like new build vs. service group splits. Next, John Downey looks into the analog-to-digital transition in optical equipment, including lessons learned so far, and low latency options to consider along the way if considering 5G backhaul services. Venk Mutalik brings it home with field details about new optical architectures and technologies that integrate with a vCMTS/DAA switch on one end, and distributed nodes at the other, as a way to economically and sustainably increase capacity during DAA builds.
