To future-proof their networks, North American cable operators need to look to a distributed access architecture (DAA) accompanied by a "fiber-deep" framework to transform their headends and outside plant.
- DAA will support higher (and symmetrical) bandwidths while lowering opex costs related to the headend.
- Various technologies previously housed in the headend can be disaggregated and then systematically integrated in a DAA approach – upgrades can be done in stages.
- "Fiber deep," or pulling fiber closer to the end user, has an important role to play in DAA.
Features and Benefits
- Identifies the business case opportunities for cable operators, including reduced opex in the headend.
- Assesses the role of "fiber deep" in cable access networks.
- Analyzes the role of SDN/NFV in a distributed access architecture.
Key questions answered
- Which technologies make up a distributed access architecture?
- How does DAA keep cable operators competitive with telco FTTH offerings?
- What role does "fiber deep" have in a distributed access architecture?
