Plattville Google 320Platteville, Wis has the largest deployment in the U.S. Curtis Frankenfeld remembers the pain of early ADSL deployments but assures me those problems are not recurring. G.fast produced "No disappointments on performance. The results in the field on real cable approach the lab results." 

"The results using coax were flawless, with slightly better performance than twisted pair. The installers only had to do a small amount of repair, splitter removal and similar." Sckipio and Calix have been enthusiastic about the possibilities of G.fast over coax and now we have confirmation from a customer.

Curtis would like G.fast to support a larger vectoring group than the current 16 ports.

For now, they are only using it for smaller buildings to avoid the binder management challenges in bigger buildings. He doesn't expect higher port counts until Amendment 2/3 chips become available, possibly mid or late next year. He also would welcome a unit for buildings with fewer than 16 ports. 

They are using Calix's SDN and tying it into Century's system. Like the other U.S. telcos, they hope soon to implement  SDN widely. They've also looked at wireless alternatives to G.fast. Verizon is doing 5G highband and calling it "wireless fiber." So far, he sees both positive and negative 

I'm not going to move to Wisconsin but sure would like the 500 megabits, especially the fast upstream.

PLATTEVILLE, Wis.Sept. 12, 2016 /PRNewswire/ -- CenturyLink, Inc. (NYSE: CTL), a leading broadband services provider in the United States, today announced that it has installed G.fast technology in Platteville, Wis., resulting in the largest G.fast deployment inNorth America. Using existing copper and internal coaxial cable infrastructure, CenturyLink installed G.fast technology in 44 multi-dwelling units (MDUs) to provide internet speeds of up to 500 Mbps and higher to nearly 800 apartments in Platteville.

"CenturyLink's commercial G.fast deployment in Platteville, Wisconsin is the largest single G.fast implementation in the U.S. to date, highlighting the company's commitment to delivering ultra-broadband services – including Gigabit access – to its customer base," saidErik M. Keith, principal analyst of broadband networks and multiplay services at Current Analysis. "With the ongoing evolution towards unicast, OTT streaming video services, including 4KTV, demand for ultra-broadband connectivity continues to escalate. To this end, CenturyLink is leveraging extensive fiber network build-outs in conjunction with key endpoint technologies, with G.fast providing de facto FTTH services over existing copper access lines."

In 2015, CenturyLink deployed fiber-to-the-premises technology to the majority of residential and business customers in Platteville to upgrade the CenturyLink Televideo TV service to CenturyLink® Prism® TV service. That fiber network enhancement also enabled most residential and business customers in Platteville access to broadband speeds up to 1 gigabit per second. Many apartment complexes in this area that did not have access to those faster speeds are now able to connect to speeds up to 500 Mbps and higher, and to Prism TV service, through this G.fast deployment.

"We saw a great opportunity to use existing copper assets in our Platteville network to bring ultra-fast internet speeds to customers who live in areas that typically don't have access to these new broadband technologies delivering higher speeds," said Aamir Hussain, CenturyLink executive vice president and chief technology officer. "We take a fiber-first approach when deploying faster broadband speeds but enabling G.fast over copper infrastructure helps us reduce costs, speed time to market and effectively connect our customers to the power of the digital world in areas where fiber deployment is less feasible."   

CenturyLink is evaluating other locations, beyond MDUs, where G.fast technology can be used to give customers access to faster speeds, such as fiber-fed multi-tenant units (MTUs) and neighborhoods where fiber-to-the-curb (FTTC) allows for G.fast to push higher speeds over the short amount of copper into the home. CenturyLink is utilizing other new technologies on its existing network infrastructure to accommodate the growing broadband needs of its customers, including the delivery of internet speeds up to 100 Mbps to nearly 1 million homes and businesses using VDSL2 vectoring.

CenturyLink is utilizing the Calix AXOS G.fast solution for its G.fast deployment in Platteville, with all systems and services managed via the cloud through Calix's Compass Consumer Connect Plus software.

Deutsche Telecom: 35b Supervectoring Delayed to 2019 http://bit.ly/35blater
Broadcom is now over 3 years late. DT briefed German reporters after their financial call and revealed 35b was now delayed until 2019. 35b should deliver 200+ meg downloads 500-600 meters, a crucial tool for DT, which is losing share to cable. Cable now covers about 70% of Germany and is expanding. DT now only offers 50-100 megabit DSL while cable is often 400 megabits, going to a gigabit. 

The problem is software; the hardware is shipping and supposedly will work. DT says 35b is not ready to turn on. Broadcom in 2015 said 35b was in "production" in the press release below. Alcatel in early 2016 said to expect complete systems very soon. "35g is very similar to 17a so there should be little delay."

Broadcom's problems are leading major telcos and vendors to have a plan B, using Sckipio G.fast. DT itself is planning extensive G.fast deployments in 2019, mostly in apartment buildings. http://bit.ly/35blater

Gigabit 100 Meters - Unless the Wires are Lousy http://bit.ly/gflousy
Speeds are fine, "Unless there's a line problem." I've been reporting for three years that ~10% of lines have problems. In the chart by Rami Verbin of Sckipio, he finds G.fast goes ~130 meters on good lines. Poor lines have about half the reach. 

His chart roughly matches the reports from Swisscom, Belgacom, and England for both G.fast & vectored DSL. The 10% with problems can cause the majority of the line-related complaints to support. The angry customers drive up cost.

Rami's solution to reach the gigabit is bonding, supported on the Sckipio chips. Verbin made some additional points:

  • 4 gigabits is possible by bonding two decent 2 gigabit lines.
  • Even in a service from remote cabinets, ~25% are close enough to get a full gigabit."
  • cDTA and iDTA are practical ways to deliver much higher upstream by switching some bandwidth from downstream to upstream only when needed.
  • 35B will probably be similar but Deutsche Telecom doesn't expect to deploy until 2019. http://bit.ly/gflousy

AT&T Wants Coax 2-5 Gigabit G.fast. Very Soon. http://bit.ly/ATTCoax
AT&T faces intense competition from cable, talking about 10 gigabits in both directions. (Cable will only be 1 gig down, ~100 meg up, until ~2021.) AT&T wants something to brag about as well.

AT&T gained millions of lines of coax as part of the DirecTV deal. Alcatel and Huawei are leading the development of G.mgfast. That uses 424 MHz, full duplex, to achieve ~2.5 gigabits in both directions. The reach on telco twisted pair is only about 30 meters. On coax, those speeds can probably extend far enough to service most apartment buildings. Using 848 MHz, speeds can reach 5 gigabits. The ITU standards group has been aiming for 2019-2020 for G.mgfast, too slow for AT&T's marketers. David Titus wants a high-speed standard for coax "early in 2018." He believes that is "doable."http://bit.ly/ATTCoax
