Our Applications & Solutions

Remote PHY Node (RPN)


The Harmonic cOS® Ripple-1 Remote PHY node (RPN) is a hardened outdoor enclosure for networks tasked with delivering video, data and voice services over coax.

Compact and cost-effective, the Ripple-1 RPN houses the cOS Pebble-1 Remote PHY device (RPD), which supports distributed access architectures defined by CableLabs® MHAv2 specification. Two Pebble-1 RPDs can be installed in a single Ripple-1 node.

Ripple-1 and Pebble-1 are both part of the Harmonic cOS software-based CCAP system, which also includes cOS Core CMTS software and the NSG™ Pro cable access platform. Fundamentally changing the business dynamics of cable delivery, cOS introduces cable operators to unprecedented scalability, agility and cost savings. The end-to-end solution supports centralized and distributed cable access architectures that enable the fast deployment of IP-based and legacy data, video, and voice services — and sustainable capacity growth. All cOS components work together to resolve space and power constraints in the headend and hub, eliminate dependence on hardware upgrade cycles, and provide multi-dimensional scaling.


• Hardened enclosure for one or two cOS Pebble-1 RPDs
• Supports up to 1218 MHz forward and 204 MHz return bandwidth
• Modular RF launch amplifier with four high-output level ports (64 dBmV/channel)
• Available lower output RF launch amplifier for BAU applications
• Remotely configurable forward gain and tilt
• Remote controlled return mute switch/attenuation for ingress control
• Hybrid disable configuration to conserve power on unused ports
• Modular single or dual Remote PHY modules for network growth with automatically configured segmentation
• Modular single or dual power supplies for redundancy and load sharing
• Power passes through two configurable AC buses, uninterrupted during module swap
• Fiber entry ports on both sides of the housing, with fiber management tray and channel for easy access
• Last gasp alarm – Power Supply monitors the AC input voltage and provides status alarm when voltage drops below minimum operating range
• RF Trays provide easy plant upgrades with offering field replaceable Diplex Filters. Diplex Filters can be swapped in the field for plant expansions
