Cisco, Arris and Teleste are among the technology vendors showing the latest enhancement to DOCSIS 3.1 broadband delivery.
The Remote PHY technology enables tremendous data capacity, robust transmission and cost-effective deployment options in HFC networks.
The CableLabs-specified technology is expected to take a significant role in the forward development of the cable sector.
Finnish tech firm Teleste has focused on promoting cross-vendor interoperability and standards-based development of RPD devices to drive the realisation of Remote PHY solutions. Its recently tested Remote PHY technology in cooperation with Cisco, which has worked with CableLabs on Open Source RPD development.
“Distributed Access Architectures (DAA) offers cable operators worldwide the ability to provide scale, flexibility and performance for their cable access networks. Remote PHY is a foundational, standards-based architecture, that enables a transition to virtualized access solutions, and offers significant TCO benefits, explains Daniel Etman, Director of Product Marketing, Cable Access Business, Cisco.
Teleste is showing delegates to CableTech in Denver its first Open RPD specification-based node, the AC91000. “From previous DOCSIS implementations, we have learned that open, standards-based development is the key to success for both operators and vendors. Interoperability of RPD devices and CCAP cores from different technology vendors guarantees that MSOs will be able to safely invest in future development of their networks and services,” said Hanno Narjus, SVP of Network Products, Teleste.
Meanwhile, in another collaboration with Cisco, ARRIS is demonstrating interoperability with each other’s Remote PHY (RPHY) solutions, including CCAP core technology and PHY nodes.
“Remote PHY delivers on the Distributed Access Architecture (DAA) promise to provide Next-Generation broadband services with improved performance and efficiency while providing a path to virtualization,” said Dan Whalen, President, Network & Cloud, ARRIS. “ARRIS and Cisco’s Remote PHY interoperability means that our service provider customers can more quickly realize the benefits of the latest IP architecture.”
Remote PHY allows for a reduction of power, cooling and hub site sizing, providing significant total cost of ownership (TCO) benefits to cable operators. Silicon manufacturers, technology vendors and global cable operators have endorsed the Remote PHY architecture and are working toward a common goal for distributed access architecture (DAA).
