In 2016, G.fast looked very promising.
But only BT & Australia's nbn remain

PLDT spending $40M over three years. 500 buildings will be connected in 2017, half business and half residential. They plan 1,600 more buildings in 2018 & 2019. They promise "up to 600-700 megabits." That's realistic; today's G.fast from the basement or the roof will usually deliver 500-800 megabits.
The surprise is the inclusion of Korea Telecom's GiGa Wire using Marvell's G.hn chips. KT itself is rolling out millions of lines of G.hn, possibly faster than the worldwide roll of G.fast. G.hn can deliver high speeds without much of the cost and complexity of G.fast. G.fast engineers believe G.hn will encounter severe congestion problems as the networks add more subscribers because of the lack of vectoring. Chano Gomez of Marvell claims real world results are just fine. I'm waiting for some independent data.
Huawei is supplying the G.fast gear,
presumably with their usual Broadcom chips. Broadcom has made many promises for their newer chips, but field results are lacking. All the chip vendors and system houses are working furiously on exceeding the current limits of G.fast (16 ports with Broadcom, 24 with Sckipio.) Until then, G.fast in larger buildings has extra costs. (16 ports are not enough to serve a single floor of Jennie's building, not unusual in New York and many other cities.)
PLDT has announced this as a "roll-out" so I'm adding them to the G.fast map. A few hundred thousand lines in three years are only a small fraction of PLDT's 6M homes passed with copper. $40M is less than 2% of PLDT's three year capex, making this a very small commitment.
PLDT now passes 2.5M homes with fiber home, more than either British Telecom or Deutsche Telekom.
PLDT to roll-out fiber-fast broadband on regular phone lines
MANILA, PHILIPPINES (19 December 2016) – Philippine telecoms and digital services leader PLDT is bringing fiber-based broadband services to the next level by deploying the latest advanced hybrid fiber technologies that can deliver super-fast broadband service through regular phone lines in buildings and residences.
The deployment comes after the successful trials of two advanced hybrid fiber technologies, one by KT Corporation (formerly known as Korea Telecom) called "GiGa Wire" and the other is by Huawei Technologies Co. Ltd. called “G.fast." Both are capable of providing data speeds per user of up to 600-700 Mbps per user, depending on the length of the local copper loop.
Both GiGa Wire and G.fast work by connecting buildings and dwellings with fiber optic cables and using special equipment to enable the internal copper wiring of these structures to deliver fiber-like data speeds.
“This new initiative is part of our broad effort to make fiber-powered, high-speed connectivity more widely available to the public. It’s part and parcel of building the ‘Gigabit Society’ – where high-bandwidth, low-latency digital services in homes, businesses, healthcare services, utilities and schools become an integral part of daily life,” said PLDT Chairman and CEO Manuel V. Pangilinan.
“Our initial plan calls for deploying Giga Wire and G.fast solutions in over 500 buildings in different parts of the country next year. This number will be split between residential and office buildings. But this is just the start,” said PLDT Chief Revenue Officer Ernesto R. Alberto.
An additional 1,600 buildings are being lined up for 2018 and 2019. Total investment in this 3-year deployment will amount to about P2 billion.
For PLDT, these hybrid technologies offer a way to take full advantage of the company’s extensive telephone network in order to deliver fiber-powered broadband services.
The vast majority of office and residential buildings are currently wired internally with copper. And it is difficult and costly to re-wire these structures with fiber.
Also, the majority of homes are still connected by regular phone lines. In the case of PLDT, -- the number of “homes passed” – i.e., the number of homes that can be reached by PLDT’s regular phone lines – is 6 million.
“Hybrid fiber technologies break down barriers to fiber deployment. These enable us to extend more quickly super-fast broadband services to areas where fiber deployment is difficult. We side step the challenge of having to re-wire buildings,” said PLDT Chief Technology and Information Adviser Joachim W. Horn.
The deployment of hybrid fiber solutions complements very well the ongoing roll-out of fiber-to-the-home (FTTH) connections. Currently, the number of “homes passed” by PLDT’s FTTH network is 2.5 million.
“With these two parallel and complementary roll-outs, PLDT is well-positioned to bring high-speed broadband to more areas of the country more quickly and efficiently than anyone else,” Horn said.
