For just $5 or $10 more, it's a no-brainer to go 10G and let GPON fade away. A world class telco tells me they will switch in 2019. Xavier Niel's Salt tells me customers love the 10G. Poland's Inea is ready to serve 30,000 homes. (below) Jeremy Chelot's Community fibre has reached almost as many in London and has raised 40 million £. Hong Kong Broadband is well ahead. Frontier in the U.S. is upgrading some of the Verizon BPON lines they bought. 

AT&T has supported an Open Source 10G ONT and done extensive trials. If they deploy, that could be five million lines/year. Adtran is making a big push to displace Nokia. (pr below) Back in August, they told me 10G was a no-brainer. They now are proclaiming that to the world at BBWF. Huawei has confirmed to me how close the prices are to volume buyers. Nokia is staying mum, as they do so often these days.

Tom Rutledge, the CEO of Charter, has 25 million cable customers, nearly all of whom can get a gigabit. Comcast has 30 million. That's why AT&T is building gigabit fibre at the fastest pace in the western world; cable is killing them in the old DSL areas. Rutledge is telling Wall Street he's not worried about telco gigabits. "Fibre is going to 10 gigabit upstream and down." Soon.

Rutledge is a top pro, but he should talk to his engineers. DOCSIS is currently delivering one gigabit downstream, usually with a two gigabit shared pipe. That's working well for him; they added 260,000 broadband subs, "the best 2Q result in 10 years." Comcast, "had the best broadband net adds in 10 years for a 20-year-old product."*

While the optimum capacity of DOCSIS can be ten gigabits, much of that will be needed for video. The most upstream Charter would sell me was 20 megabits, which wasn't enough for Jennie's video. Like all the cablecos, they delayed modernizing the DOCSIS upstream. Full duplex DOCSIS is on track for trials in 2019 and deployments in 2020, but requires a hardware upgrade, a remote phy near the customer. It will take years to deploy across a network the size of Charter or Comcast. Verizon and AT&T will have a major upstream advantage well into next decade across 50% of the U.S.

Rutledge also needs to listen to his competitive intelligence people. He made a mistake at a recent conference, saying Verizon would take 10 years to reach the 30M homes in the first wave of millimeter wave. Actually, Verizon intends to offer an mmWave alternative to 1/4th of Rutledge's customers by 2022 or 2023. Vestberg has said he will reach "The entire country" in ten years. (Entire country is usually 90%-95%.) I don't know Tom but considered sending this note via mutual friends. I held back, sure his IR people would catch it. 

The primary use of 10 gigabit DOCSIS will be to run speedtests to show your neighbors how fast you are. I downgraded from 200 megabits to 100 because I didn't need it. A gigabit will be overkill for years for almost everyone. But people buy higher speeds, carriers are finding worldwide. Salt is taking enough customers to scare Swisscom, although they haven't released figures yet.  

The difference in cost is so low you can and should take it out of the marketing budget.

From now on, approximately 30,000 households in Poznań can use the 10 Gb/s connection offer. By the end of the year, INEA plans to make such a possibility available in the entire city and ultimately also on the FTTH INEA network. The symmetrical Fiber-To-The-Home (FTTH) connection with data transfer speeds of up to 10 Gbps is offered at the price of PLN 399. Apart from Poland, only the residents of Switzerland and several cities in the USA, Japan, South Korea and Singapore[1] can use such a fast Internet connection."INEA has always focused on innovation. The technology is developing at a dizzying pace, and we don't want to limit our customers. We have proved several times in our history that we are the technological leader, and today is the time for the next step,” says Michał Bartkowiak, Chief Operating Officer INEA. "It is worth emphasizing that the symmetrical link we offer will allow IT specialists, artists, people involved in video processing or new technologies such as virtual or augmented reality, to work freely at home. From now on, remote work will not be a problem for them. And it is not our last word on this issue yet," adds Bartkowiak.The launch of a 10 Gb/s link in Poland was carried out jointly with Nokia, which provided a next-generation fiber solution capable of delivering symmetrical speeds along with the added network capacity, reliability, flexibility and scale needed to deliver enhanced ultra-broadband services in the future.

These devices operate using the FTTH INEA network.The 10 Gb/s Internet offer is addressed to people who, when pursuing their hobbies or professional challenges, want to both download and transmit data at a speed previously unavailable in Poland. The symmetry of the link results in the fact that the transfer of such data in both directions takes place in a flash. Such a fast Internet connection will be also appreciated by players. The latest productions can occupy several dozen gigabytes of disk space, which means that even on the currently offered lines, their downloading takes long enough to make it noticeable. With a 10 Gb/s connection, this time will be significantly shortened. For example, the most awaited game of 2018, Red Dead Redemption II, which will occupy approximately 100 GB, can be downloaded in less than 2 minutes using the INEA connection.

Thanks to INEA, from now the limitation is not the speed of the connection, but the technological capabilities of terminal devices (computers, consoles) available on the market. Thanks to the innovative XGS-PON technology introduced, one should also expect very low pings, i.e. the time necessary for the signal to pass from our device to the server and back, which is of key importance for on-line entertainment.

Expanded 10G Fiber-to-the-Premises (FTTP) portfolio enables Gigabit Society

HUNTSVILLE, Ala.--(October 15, 2018) ADTRAN, Inc., (NASDAQ:ADTN), the leading provider of next-generation open networking solutions, today announced the addition of the ADTRAN SDX 621X—a residential optical network terminal ("ONT")—to its portfolio of next-generation 10G PON business ONTs. The expanded FTTP solution set allows carriers to provide multi-gigabit services for everyone, everywhere and maximize existing optical distribution networks to save time and costs.

The new ADTRAN SDX 621X supports symmetrical 10G PON technologies and uses a flexible optics approach that enables service providers to support existing fiber-to-the-home (FTTH) subscribers, while also simultaneously supporting higher-bandwidth business and 4G/5G “anyhaul” services over a single, common network.

The ADTRAN Total Access 5000 fiber broadband platform combines integrated packet optical transport, 100G switching, combined with PON redundant multi-gigabit FTTP broadband service delivery to allow operators of all sizes to customize their network and introduce next-generation fiber technologies. The addition of the ADTRAN 621X residential subscriber end-point to this industry-leading platform further extends ADTRAN’s 10G PON leadership for service providers of all types and opens the door to mass market 10G PON deployment.

"The original use cases for 10G PON focused on multi-gigabit enterprise and infrastructure backhaul services, given the high costs of 10G PON ONT optics,” Ovum Principal Analyst Julie Kunstler said. “Technical innovation, as seen within the ADTRAN 10G PON solution, along with economies of scale spurred by 10G deployments globally, are driving down the cost difference between GPON and 10G. Consequently, 10G PON is now a viable option for residential subscriber deployments, and operators understand the competitive and future-proofing benefits of moving to 10G."

The ADTRAN SDX 621X ONT offers a compelling multi-gigabit, symmetric alternative to single gigabit capable GPON, EPON, Gfast and DOCSIS 3.1 services being deployed today and is supported by the ADTRAN Mosaic Subscriber Experience suite, allowing service providers to monetize the subscriber edge while improving customer loyalty and operation efficiency.

Emerging high-bandwidth applications like high-resolution 360º video, autonomous vehicles and fully-immersive applications are set to consume the capacity levels supported by today’s 1G PON broadband connections (GPON and EPON). 10G FTTP architectures extend the life and profitability of a PON network infrastructure. Fixed wavelength, symmetric 10G PON technologies now offer compelling economics for global mass-market fiber deployments, and service providers with even greater capacity needs are already choosing multi-wavelength 10G PON technologies based on ITU-T NG-PON2 standards. Both 10G PON technologies allow service providers to access more of the near-unlimited bandwidth of optical fiber than before, delivering high-end services over a cost-effective PON architecture that previously required a more expensive point-to-point fiber build.

"The demand for higher capacity fiber access will continue to grow as new applications enter the market and operators look to increase efficiency by converging all services onto a common infrastructure,” ADTRAN Portfolio Director for Fiber Access Ryan McCowan said. “With 100G switching, 10G access, and now mass-market 10G CPE, covered by end-to-end open service orchestration, ADTRAN is leading the next wave in fiber broadband."
