Remote PHY Device


COMMSCOPE provides both the CCAP Core and Remote PHY Device (RPD) defined in the CableLabs Modular Headend Architecture (MHAv2). In this approach, the PHY layer is moved from the CCAP into a node or remote shelf, but the MAC processing, provisioning, and monitoring functions remain in the headend.

The E6000 CCAP Core runs on the Gen 2 E6000 hardware platform (E6000 Chassis, RSM-2, DCAM-2, and UCAM-2). The RPDs are add-in modules for existing COMMSCOPE nodes.

COMMSCOPE supports three RPD form factors: E6000n RPD for the OM6000 Fiber Deep node, E6000n RPD for the NC4000 and NC2000 nodes, and E6000n RPD for Remote PHY Shelf.

Generating RF signals in the fiber optic node rather than in the headend can provide a cost-effective tool for:

  • Improving plant signal quality
  • Improving fiber utilization and reach
  • Improving service group density in the headend
  • Reducing space and power consumption in the headend
  • Simplifying plant maintenance by using digital optics
  • Reducing transmission costs by leveraging data center economies of scale for Ethernet switches and optics

Applications for DAA:

  • Plant upgrade for DOCSIS 3.1 support
  • Hub consolidation
  • Enabling Fiber Deep deployment without requiring headend expansion
  • Utilizing DWDM optics for long distance links
  • Supporting data services in small hubs
  • Simplifying logistics for changing US / DS split or top-end frequencies

The E6000n RPD comes in three variants:

  • E6000n RPD for the OM6000 fiber optic node housing
  • E6000n RPD for the NC2000 / NC4000 fiber optic node housing
  • E6000n RPD for Remote PHY Shelf

For operators with smaller hub sites or cabinet-based architectures, the Remote PHY Shelf can optimize overall power requirements while supporting up to three Downstream service groups and six Upstream service groups.
