Buried deep in an SDAN announcement is a mention of a Lightspan SX-16F. They call it  "The world's first 16-port reverse-powered micro-node which can be safely reverse-powered from the home." No more details available at press time.

Australia talks about running fiber to a distribution point close to homes. Since it's expensive to bring in electric as well, reverse powering should be very attractive to Australia's NBN. Adtran beat Nokia to the NBN contract so presumably will announce something soon.

If Nokia doesn't get more details, like delivery dates, ask the NBN folks at BBWF. They have no reason for secrecy. 

Alcatel introduced Vplus 35b at BBWF two years ago, to ship in 2016, Deutsche Telekom says it won't be ready for service until the second half of 2018. 

Judgment has to wait for results from the field.

Here's Alcatel two years ago on 35b and also the new Nokia SDN. There are so many conflicting claims in SDN and so little evidence I rarely report it. I prefer to know what I'm writing about.

Alcatel-Lucent introduces industry’s first Vplus products to fill gap between and VDSL2 Vectoring technologies

New ‘Fiber-to-the-Cabinet’ technology delivers higher speeds over longer distances enabling operators to provide ultra-broadband access to more homes and businesses

Broadband World Forum 2015, London, United Kingdom, October 20, 2015

Alcatel-Lucent (Euronext Paris and NYSE: ALU) today launched the telecommunications industry’s first commercially available products based on Vplus technology, enabling operators to accelerate the deployment of ultra-broadband access and increase their ability to meet demand for faster data speeds in homes and the workplace.  
With demand for – and competition to provide - ultra-broadband access accelerating at unprecedented rates, operators need timely, cost effective options to meet consumer expectations for enhanced speeds and capacity. Vplus, a DSL technology initially introduced by Alcatel-Lucent and now being standardised as the VDSL2 35b profile by the ITU-T, delivers this for operators.  Designed to be added to existing VDSL2 vectoring networks without impacting performance, Vplus allows operators to deliver aggregate speeds of 200Mbps and more over traditional copper telephone lines at distances up to 500 meters, and 300Mbps on loops shorter than 250m. 
With higher bitrates than VDSL2 17a and longer distances than, Vplus provides operators with a simple way to gain the flexibility needed to meet demand for ultra-broadband access. The high port density of Vplus also allows operators to use existing cabinets to gain additional cost efficiencies without having to run fiber all the way to the premises or distribution point. To help further ease migration efforts, Alcatel-Lucent’s new Customer Premise Equipment (CPE) will support VDSL2, Vplus and technologies, allowing operators to switch to a new DSL technology without having to upgrade the CPE.  
Alcatel-Lucent’s new range of Vplus products is part of a complete portfolio of ultra-broadband access solutions that are helping operators such as A1 in Austria address customer demand for high-speed services.
Commenting on the introduction, Marcus Grausam, CTO of A1 said: “Ensuring we can provide our customers with the best possible ultra-broadband services are a top priority for A1. Alcatel-Lucent plays a critical role in helping us achieve that vision. With their help we were the first to trial and launch using vectoring technology and are one of the first to connect live customers using Vplus as part of committed effort to more effectively serve our subscribers needs.”

    Stephen Wilson, Principal Analyst at Analysys Mason said: “Operators are using a combination of fiber and copper technologies to accelerate ultra-broadband access and help bring gigabit services to subscribers. New FTTC-orientated technologies like Alcatel-Lucent’s Vplus solution along with VDSL2 Vectoring and technologies are providing service providers with a wide range of FTTx solutions that all play an increasingly important role for those seeking to quickly offer enhanced ultra-broadband services.”

    Nokia redefines fixed access virtualization with cloud-native and software-defined products Altiplano and Lightspan

  • Nokia automates the fixed access network and unlocks new capabilities with virtualized access platform Altiplano to support widest range of software-defined use cases
  • Nokia Lightspan programmable access nodes drive new deployment practices for central office, data center and copper/fiber outside plant to build open and scalable access networks
  • Nokia takes lead in industry specifications and open-source initiatives to accelerate adoption of software-defined access networks
  • 09 October 2017

    Espoo, Finland - Nokia today launched its new Software-Defined Access Network (SDAN) solution, a comprehensive set of cloud-native software, open programmable hardware, scalable deployment practices, automated operations and integration services. Leveraging Nokia's work with industry bodies, open source initiatives and extensive collaboration with leading service providers, SDAN enables operators to build pragmatic solutions and avoid vendor lock-in as they tackle surging customer demand.

    This end-user and policy maker demand for broadband is driving operators to add more bandwidth, more connections and more technologies, meaning increasing complexity in the network. SDAN is the key to making the access network smarter, so operators can manage cost and complexity and renew their ability to scale. Rather than apply virtualization for virtualization's sake, SDAN harnesses cloud intelligence and programmability to support concrete use cases that bring the most value to operators - such as network slicing, virtual access networks, data center practices, wavelength mobility, cloud-based provisioning, automated operations and edge cloud architectures to enable 5G and IoT applications.

    Nokia's cloud-native software platform, Altiplano, is uniquely designed for the SDN/NFV space, renewing operators' ability to scale by centralizing and virtualizing network functionality that was traditionally embedded in the access equipment. Altiplano offers intuitive business logic to cut across traditional network management silos and auto-align the network. Leveraging open interfaces, open data models and open industry initiatives such as Open Broadband ON.LAB Open NetworkingFoundation (ONF), CORD ONAP and BBF , Altiplano allows operators to integrate Nokia SDAN easily in a multivendor environment.

    The Nokia Lightspan family delivers programmable access nodes, specifically designed for SDAN use cases, which bring data center practices to the central office and introduce cloud and operational agility to the copper/fiber outside plant. The innovative and compact Lightspan hardware comes with powerful processing, increased throughput and power-efficient design. It features the Lightspan SX-16F, the world's first 16-port reverse-powered micro-node which can be safely reverse-powered from the home. It also includes the Lightspan CF-24W, a stackable software-defined optical line terminal (OLT) that delivers the industry's highest next-generation PON (NG-PON) capacity in a single one-rack unit.

    SDAN is driven by real world use-cases defined by cooperation with leading operators from around the world like du, nbn, and SK Telecom, to name just a few of the more than 30 trials and demos Nokia has been conducting. SDAN is an essential part of Nokia's Intelligent Access vision, a new generation of broadband where networks are not only faster but also better and smarter.

    Teresa Mastrangelo, Principal Analyst at Broadband Trends, said:"While fixed access operators across the globe are raising the bar on ultra-broadband coverage, it's no longer enough to just make networks faster. Nokia SDAN lays the foundation for fixed operators to change the economics of their business with cloud agility and software-driven automation. Nokia SDAN is putting virtualization to work, focusing on real-world benefits for operators and end users, addressing investment protection and improving scalability with industry-leading powerful access nodes. With this announcement, Nokia has the opportunity to lead operators into this new era of software-defined access networks."

    Federico Guillén, president of Nokia Fixed Networks, said: "Nokia focuses on areas where virtualization provides concrete benefits to operators. We deliberately go for an open, standardized, vendor-agnostic approach that smoothly integrates legacy as well as new cloud services. Our fixed access virtualization portfolio now covers copper, fiber, coax networks and professional services, which makes us ideally placed to transform the operator's network, operations, and business just as the opportunities of 5G begin to accelerate."

    Nokia will showcase its Intelligent Access portfolio at the Nokia Booth E104 at the Broadband World Forum in Berlin, October 24-26.

    The Site for gfast 230

    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.

    Deutsche Telecom: 35b Supervectoring Delayed to 2019
    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 DT itself is planning extensive deployments in 2019, mostly in apartment buildings.

    Gigabit 100 Meters - Unless the Wires are Lousy
    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 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 & 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.

    AT&T Wants Coax 2-5 Gigabit Very Soon.
    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."
