Dark Green: Firm commitments from incumbent: BT (10M), Belgacom, Australian NBN, Swisscom,  Austria, Bezeq Israel, Chunghwa Taiwan, Telus Canada, Telekom South Africa, SK Korea, (U.S.) AT&T, Century, Frontier, Windstream, Belgium, Omantel

Mid Pink: Smaller carriers in Germany, Norway, Finland, Japan

Light Green: Incumbent likely:  France, Germany, Italy

The headline is the whole story. Two North American telcos have told me they need a smaller unit. They don't want to pay for 16 ports when they only need 4 or 5. Nokia has announced one. The unit is shipping.

Price is undisclosed, which means the price is based on how hard you negotiate and how much Nokia wants your business. Alcatel used to have deals with large carriers for a flat per port price no matter which size DSLAM they are using. I don't know if they still make that offer, but the customers loved it. 

There's very little to say here. The market wants the product so I'm including it.

I would love to add to this report that Nokia's new gear supports longer loop lengths, as they claim below. Unfortunately, they don't say longer than what, provide an estimate of rate/reach, or release test data.

If it reached longer than their last generation of G.fast, that wouldn't be news. All the chipmakers have been improving their early chips. Everyone's getting better.

If it's significantly longer than other vendors, that would be very interesting. The last independent data I have is about five months old. An outfit I trust found that units based on Broadcom chips (like Nokia) did about as well as those with Sckipio chips. I'd love to have more recent, reliable test data.  

Nokia expands G.fast deployment options, facilitates massive roll-outs for operators

October 13, 2016

Press Release

  • Nokia extends G.fast micro-node portfolio with solutions that provide higher densities and longer looplengths from cabinets and distribution points

  • Nokia brings programmability and automation to the copper access network to accelerate G.fast deployments by 50 percent

  • Software-defined networking and network function virtualization (SDN/NFV) improve accessibility, serviceability and turn-up time

Espoo, Finland – Nokia has expanded its portfolio of G.fast micro-nodes to help operators accelerate ultra-broadband deployments and deliver faster data speeds to end-customers using existing copper networks. The G.fast micro-nodes provide a simple, flexible plug-and-play solution that can scale in line with demand, allow for both distribution point and cabinet deployment models and cut roll-out times in half.

Service providers are increasingly turning to technologies like G.fast, which uses existing copper networks to deliver fiber-like speeds to customer over short distances, to meet growing demand for gigabit services. However, to achieve these speeds, G.fast technology typically requires the deployment of micro-nodes to be installed close to end-users. This can be challenging for operators to deploy, configure and manage at scale.

To help operators scale and accelerate G.fast deployments, Nokia is strengthening its portfolio of micro-node solutions to help:

  • Deploy more G.fast – Nokia’s industry-leading transmission and vectoring technology allows operators to deliver G.fast over longer distances and to more users from a single node. As a result, G.fast can now be used from cabinet, pole, manhole or in-building locations, providing a range of cost-effective deployment models.

  • Deploy G.fast quicker -Zero-touch provisioning allows operators to quickly power up and auto-configure each node and avoid local software loading and local provisioning. This provides a “connect-and-go” option which reduces time of deployment by 50 percent.

  • Deploy G.fast better - Accessibility and serviceability of G.fast micro-nodes is improved with SDN/NFV and NETCONF/YANG capabilities. Nodes are pre-provisioned from the cloud  and seamlessly deployed in the network. This helps operators to efficiently scale and manage the network from any location.

Federico Guillen, president of Nokia’s Fixed Networks business group, said: Nokia’s G.fast micro-nodes enable operators to further extend the benefits of G.fast without the added complexity or time once required to do this. Flexible deployment options for both larger and smaller systems are key to optimizing the business case for massive G.fast roll-outs. We also use SDN/NFV to simplify and automate the management process and deliver tangible benefits to operators - allowing them to accelerate G.fast deployments and extend ultra-broadband services to more people, quickly”

Teresa Mastrangelo, senior analyst at Broadbandtrends, said: “The ability to support a wide range of use cases in a cost-effective manner is key to wide-scale deployment of G.fast. These additions to the Nokia G.fast portfolio provide operators with the necessary tools to meet these objectives in a competitive manner.”

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
