Microsemi Corporation, a leading provider of semiconductor solutions differentiated by power, security, reliability and performance, recently introduced at the Broadband World Forum (BBWF) 2014 its new reverse power feed (RPF) technology, a critical technology for FTTdp and G.fast deployments.
G.fast, the new xDSL standard for 1gbps over copper, has a maximum expected range of 250 meters (m). In order to achieve the highest data rates with G.fast, shorter loop lengths are required which leads to the need for fibre to the distribution point, or FTTdp. These fibre-fed distribution point units (DPUs) in some cases will require reverse power feed, either due to the location of the DPU, regulations of countries or economic reasons related to power grid hookup and monitoring the grid with a smart meter.
