Reverse Power Feed (RPF) is a critical technology for the upgrade of VDSL2 subscribers to the new 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.
Provides design suggestions for common circuit needs, estimates performance for common modifications, and can export to MPLAB® Mindi™ Analog Simulator for verification.
Uses a SIMetrix/SIMPLIS environment to model circuit behavior, reducing design time with software debugging for initial design verification.
Provides advice on your exact physical circuit layout, sharing best practices from an experienced power supply designer so that physical hardware will match simulations.
