Reverse Power Feed (RPF) Products

View All Parametrics

RPF Solutions for Shared Power Delivery, SPE-DPU Signalling and Per-Line Monitoring and Control

Reverse Power Feed (RPF) is a critical technology for the upgrade of VDSL2 subscribers to the G.fast standard, which has a maximum range, at high speeds, of 250m. Our RPF solution simplifies the complexity of powering a low-port-count Distribution Point Unit (DPU) by providing power from the Customer Premises Equipment (CPE) rather than from local AC mains or other remote feeding. Our RPF chipsets support power feeding from CPEs and shared power delivery and extraction at the DPU. In addition to the powering function, the firmware also manages PSE-DPU signaling, power sharing, per-line monitoring and control.
