The R-PHY unit (RPU) can now assume several roles including monitoring the upstream RF, supporting the field find and fix for technicians, and enabling return sweep including real-time field meter interaction. It also provides the downstream RF tagging needed for leakage monitoring and troubleshooting systems.
Virtualizing the upstream spectral analysis capabilities previously handled by hub-mounted hardware into the RPU enables continuity of these critical capabilities in a Remote PHY environment.
The RPU can further be leveraged to transmit and receive sweep telemetry
signaling with existing field sweep meters, enabling a common sweep
process between legacy and Remote PHY nodes. In this case, the
technician uses the same process and meter regardless of the node type
or service provision gear in use, effectively insulating the technician
from the underlying complexity.
