By adopting a distributed access architecture (DAA), service providers can disaggregate and virtualize management functions of their hybrid fiber-coaxial (HFC) access network quickly and efficiently. Through the strategic relocation of cable head-end and hub functions closer to the optical node, operators can increase bandwidth, improve fiber performance and reduce OpEx.
As the leader in advanced network architecture, CommScope offers a comprehensive portfolio of remote PHY (physical RF layer) and remote MAC (medium access control)-PHY components to fit any network. Dependable, flexible and agile, our DAA devices can immediately improve your network output while also making it future-ready.
• Boosts network capacity and speed
• Produces a higher signal-to-noise ratio—increasing quality of service
• Reduces congestion and head-end density by eliminating equipment
• Shrinks power requirements and HVAC costs at headend
白皮书：A Side-By Side Comparison of Centralized vs. Distributed Access ArchitecturesThis paper defines and compares two classes of access architectures that will emerge this decade to impact cable networking. 为了帮助 MSO 做出明智的决定，本文包括完整的评估标准以及六种不同类型接入体系架构的并排比较。
执行简报：Successful Deployment of Remote PHYOperators must embrace new technologies and architectures to meet the growing demand for bandwidth. While delivering higher data speeds, they must also find ways to generate operational cost savings. Many are adopting DOCSIS 3.1 and Distributed Access Architectures, however, Operators need to determine which combination of technologies and approaches will best meet subscriber demand over the next five to 10 years. One Danish Cable Operator discovered that Remote PHY can be a key ingredient in the transformation required to build a more efficient, scalable, cost-effective network. This executive brief explains the benefits that Remote PHY has to offer and the results that this approach has yielded for the Danish Operator.
