World’s first G.fast reverse power feeding is demonstrated
G.fast is the approved ultra broadband standard from the ITU and is expected to deliver up to 1Gbps to consumer residences. This will allow for ultra high speed Internet access as well as support streaming multiple channels of ultra HD TV (4K) concurrently. One of the key elements of G.fast is the ability to deploy it close to the home in locations that don’t currently have power for distribution points. Reverse power feeding enables operators to deploy those distribution points in more convenient locations without the need for dedicated AC power, thus allowing for more efficient and lower cost deployments of G.fast. The role of reverse power is central to many fiber-to-the-distribution-point (FTTdp) deployments of G.fast.
“G.fast is an important new market for reverse power and Sckipio is a leader in G.fast,” said Roger Holliday, senior vice president and general manager, communications products group at Microsemi. “This joint demonstration proves the feasibility and practicality of G.fast in FTTdp deployments.”
“The role of reverse power is central to many deployment scenarios of G.fast,” said David Baum, CEO of Sckipio. “With a tremendous technology partner such as Microsemi, we are accelerating the time to market for G.fast. This will make service providers, equipment makers and consumers all happy. Now, they will get the benefits of lower cost ultra broadband sooner than people thought possible.”
The demonstration shows DC power injected by Microsemi’s RPF PSE chip PD81001-based injector into the Sckipio CP1000-EVM G.fast consumer premise equipment and transmitted to an eight-port power extraction and aggregation module based on Microsemi PD70201 RPF PD chip, which safely converts the equally shared power into 12 volts for use by the Sckipio DP3000-EVM G.fast Distribution Point device.
“Validating the reverse power feeding is a critical piece of the G.fast puzzle,” said Simon Stanley, contributing analyst for Heavy Reading. “This is a major step forward in the ultimate success and adoption of G.fast.”
