Harmonic Enables Acceleration of Cable Broadband Upgrades and Capacity Expansion

Harmonic has announced CableOS Reef, a new dense Remote PHY Shelf (RPS) that fundamentally changes the dynamics of cable network capacity expansion. By fully converging IP-based data, video and legacy services in centralised or remote facilities, this compact new indoor platform enables operators to more swiftly and economically address capacity issues while still leveraging their existing HFC outdoor access networks.

“As upstream bandwidth utilisation peaks, today’s operators need a fast, cost-effective and sustainable solution for expanding network capacity,” said Nimrod Ben-Natan, senior vice president and general manager, Cable Access Business at Harmonic. “CableOS Reef RPS builds on the growing success of our CableOS solution by defining a new category of DAA that helps operators scale bandwidth rapidly utilising their existing HFC network. With this future-proof solution, operators don’t need to continue deploying costly legacy CMTS to address immediate bandwidth capacity issues. Instead, they can leverage modern technology to realise instant scalability, agility and cost savings.”

With Harmonic’s CableOS Reef RPS, a cable operator’s services are converged over IP and transmitted from a single RF port, saving significant wiring, space and time when a node split is needed. Housing up to nine modular line cards in two standard rack units, each with two independent Remote-PHY devices (RPDs) for a total of 18 RPDs, CableOS Reef RPS delivers significantly increased density relative to existing solutions and unprecedented low power consumption per service group.

CableOS Reef RPS extends Harmonic’s Pebble-inside family of R-PHY devices, which also includes the modular Ripple node. As the only field-proven R-PHY node that provides 2×4 segmentation, the Ripple node also accelerates capacity expansion through efficient node splits, with the capability to host up to two RPDs while consuming significantly less power than traditional solutions. Harmonic’s family of R-PHY devices – the Reef shelf, Ripple node, Shell node and Wave shelf – now cover every cable access deployment scenario, providing unified functionality and unprecedented flexibility as operators address the urgent need for more bandwidth today and in the future.
