adtran 212Demos double frequency G.fast and cDTA with Deutsche Telekom. Adtran only claims "gigabit rates" but the technology is designed for over a gigabit and a half, combined upstream and downstream.  I infer from their comments they are ready to ship. They also claim good performance from DTA, rapidly shifting upstream and downstream ratios based on traffic demands.

Sckipio's supplying the chips for cDTA, according to Richard Chirgwin in The Register. With the DTA now working on ordinary twisted pair. Telcos to claim "effective speeds of 500 upstream, 500 downstream." G.fast from fiber to the basement or wireless to the rooftop now outshines gigabit DOCSIS, especially on the upstream. Few cablecos are likely to improve their upstream significantly before Full Duplex is ready next decade. Verizon is heavily advertising their 50/50 & 100/100 Fios speeds because the higher upstream is winning customers. 

Rami Verbin of Sckipio is one of the most creative chip designers I know. He's been working on continuously varying the upstream/downstream splits in G.fast. His models were very convincing and the chips have been highly anticipated.  

In a joint press release with DT, Adtran says, "ADTRAN demonstrated the new 212MHz G.fast standard, which doubles the usable spectrum. This doubling of the usable spectrum allows service providers to deliver gigabit rates over a single copper pair, enabling robust fibre-like service delivery all the way to the customer premise. In contrast to cable systems, the bandwidth of G.fast is dedicated and available for each customer. The tests, leveraging the first commercially available 212MHz DPU also demonstrated the second phase of DTA. cDTA, like the earlier iDTA feature, improves G.fast upstream performance by four to five times by dynamically balancing upstream and downstream capacity to match residential traffic patterns in real-time. cDTA also expands the applicability of this feature to existing phone wiring, thus covering nearly all residential and commercial premises." 

I've sent a note to Broadcom and Metanoia asking about their progress on 212 GHz. and cDTA, which I'll add to this article if they also have news. 

AT&T is expanding G.fast out of district, although the serious volume is a few quarters away. Century, Frontier and the smaller telcos are natural targets for T and they want to have a counter if VZ comes after them in fixed. "They will get better at it, they will get faster at it, and will be ramping." Modest volume likely until 2018.

Australia's NBN has now confirmed they are going with Adtran for a million lines of fiber to the curb. Officially, that isn't G.fast but it makes no sense to make any other choice. Also likely modest volume until 2018.

Finally, Deutsche Telekom's new management is realizing VDSL may not be enough to compete with cable and fiber. Then CTO Bruno Jacobfeuerborn in 2015 said they would go for G.fast, but the finance side veto'ed the budget. Looks like they are back in the game. G.fast is the right choice for the >5M large buildings in Germany.

Adtran had a superb quarter and these new deployments suggest business will be good at yearend. Wall Street thinks so and the stock jumped 15%. Stanton believes their SDN variant Mosaic is a powerful differentiator and reports most new customers are using it. The new contracts seem to have a large services component, which pulls down margins in the short run. 

Calix and Adtran intend to prove the report of the death of the U.S. telecom industry is premature..

For the record: Adtran will be paying my expenses to their event in Huntsville in August. I'm going to try to bring Jennie and her camera..

 

ADTRAN and Deutsche Telekom Look to Ultra Broadband Evolution to Advance the Gigabit Society

Lab trials proving latest G.fast innovations, 212Mhz and cDTA, will accelerate deployment of ultra-fast and gigabit broadband services

DARMSTADT, Germany--(BUSINESS WIRE)--Jul. 18, 2017-- ADTRAN®, Inc., (NASDAQ: ADTN), a leading provider of next-generation open networking solutions, today announced the start of lab testing of the latest innovations in the G.fast standard, 212MHz and coordinated dynamic time allocation (cDTA) together with Deutsche Telekom (DT). DT is evaluating these ultra-broadband technologies using Fibre-to-the-Building (FTTB) deployment models allowing the use of existing cable infrastructure within the home. This will allow the rapid deployment of ultra-fast and gigabit broadband services with minimal disruption. The low cost per subscriber connection pays directly into achieving European Commission’s Gigabit Society goals.

ADTRAN demonstrated the new 212MHz G.fast standard, which doubles the usable spectrum. This doubling of the usable spectrum allows service providers to deliver gigabit rates over a single copper pair, enabling robust fibre-like service delivery all the way to the customer premise. In contrast to cable systems, the bandwidth of G.fast is dedicated and available for each customer. The tests, leveraging the first commercially available 212MHz DPU also demonstrated the second phase of DTA. cDTA, like the earlier iDTA feature, improves G.fast upstream performance by four to five times by dynamically balancing upstream and downstream capacity to match residential traffic patterns in real-time. cDTA also expands the applicability of this feature to existing phone wiring, thus covering nearly all residential and commercial premises.

“Operators in highly competitive, dense urban or urban environments are challenged to extend gigabit services due to the time and cost that can be associated with pure play FTTH techniques,” said Jay Wilson, senior vice president at ADTRAN. “With G.fast innovation, operators, such as DT, can significantly accelerate Gigabit Society goals by launching gigabit services over their existing infrastructure dramatically reducing subscriber disruption.”

These two most recent G.fast advancements, 212MHz and cDTA, extract even greater overall performance from an operator’s existing assets, and in many scenarios, eliminates the need for full FTTH for years. For the first time, these G.fast innovations enable service providers to more rapidly and cost-effectively extend symmetric gigabit services and expand ultra-fast broadband to the wider market.

I’m still working through remarkable presentations from the Broadband Forum events. Michael Weissman, Bernd Hesse and team did a remarkable job choosing the speakers. http://bit.ly/BBFBASE

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
