BroadbandA new G.fast forecast calls for the technology to reach nearly 30 million homes and businesses around the world by 2021. The forecast comes from Ovum, which conducted the research for Australia’s nbn (National Broadband Network) and U.K.-based BT. G.fast aims to bridge the gap between fiber to the node (FTTN) and fiber to the premises (FTTP0 by delivering high-speed broadband over short copper loops.

Australian network carriers and ISPs have yet to introduce G.fast platforms commercially. An initial crop is expected in 2017 and penetration will expand rapidly from that point to reach nearly 29 million subscribers in 2021 – 3 percent of global fixed broadband connections, according to the ¨Gigabit Networks¨ report.

G.fast Forecast
“As an emerging technology, the growth in new G.fast subscribers is expected to accelerate each year, rising from 330,000 in 2017 to nearly 11.5 million in 2021,” the report authors predict.

NBN conducted its first G.fast trial in October 2015 and has been working with Nokia to carry out XG FAST lab trials in recent weeks. Based on the G.fast spec, XG FAST holds out the promise of 5 Gbps Internet speed over existing copper connections, but it won’t be available for several years, news.com.au reported Sept 2.

Here in the U.S., Windstream launched its initial commercial G.fast deployment in Lincoln, Nebraska in July. Windstream is employing Calix’s GigaCenter to roll out connectivity to two apartment complexes (MDUs), a total of about 550 units across 25 buildings.

Speeds will be well below one gigabit, however. G.fast semiconductor vendor Sckipio reports that G.fast speeds of 150 Mbps at 1,600 feet (500 meters) and 300 Mbps at 960 feet (300 meters) are feasible.

In addition, CenturyLink on Sept. 12 announced what it billed as North America’s largest G.fast deployment. Taking place in Platteville, Wisconsin, CenturyLink is rolling G.fast network connectivity to nearly 800 apartment units across 44 MDUs.
