In 2016, looked very promising.
Thousands worked at developing and deploying.
It wasn't enough. 
Most carriers are investing
in fiber or 5G instead.


Dark Blue: 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 Blue: Smaller carriers in Germany, Norway, Finland, Japan

Light Blue: Incumbent likely:  France, Germany, Italy

Wheres Waldo 200Shipment claims are so far ahead of sales that need an explanation. Nokia is proud they won the order from Frontier in Connecticut, a U.S. company with over 4M DSL & fiber subscribers at the end of Q1. They gave no details of when, where, or how many, so it wasn't worth a headline. (PR below)

The interesting thing in the release is the claim they've shipped, "30 million vectoring lines." I'd be surprised to discover that even 10% of those are actually deploying vectoring. Similarly, Adtran claims 10M vectored. (PR below) There are remarkably few vectored lines in service. The claimed vectored ports are probably 10x or more the number of actual vectored lines.

There just aren't many homes connected with vectoring.

 They are both honorable companies unlikely to lie on something like this. 

My first thought was that several major companies were buying DSLAMs designed for vectoring but not putting them to use. It's certainly possible that they are planning ahead. If DT, BT, and AT&T were doing that, the numbers might add up.

Alternately, it may be they are counting systems that can relatively inexpensively be upgraded. They might be through an external vectoring box or adding line cards. Informed opinion welcome. 

Whether active or not, 40M vectored ports are quite an achievement.


Nokia and Frontier Communications deploy technology to expand gigabit ultra-broadband access across Connecticut

  • Nokia technology enables Frontier to quickly roll out fiber-like speeds to customers living in apartment buildings and deliver new IPTV and data service packages

Norwalk, US - Nokia and Frontier Communications will deploy technology to increase in-building broadband speeds for customers living in apartment and multi-dwelling units (MDU) across Connecticut.

Part of a state-wide network expansion initiative, Frontier will use Nokia's technology to quickly bring fiber-like speeds to customers without having to install new, in-building fiber infrastructure. With built-in vectoring technology - which reduces cross-talk interference that typically impacts data speeds over copper networks - the Nokia solution will allow Frontier to use the last few hundred meters of existing copper located in buildings to deliver ultra-broadband access to customers.

Nokia's technology enables Frontier to complement its extensive fiber network footprint and rapidly deploy fiber to the basement of an apartment building instead of each individual apartment unit. Leveraging Software Defined Network (SDN) capabilities and compliant with NetConf and Yang models, Nokia's solution also enables Frontier to accelerate deployments by automating the management process and simplifying provisioning models.

Steve Gable, Frontier EVP and Chief Technology Officer said: "Nokia's field-proven solution will help Frontier quickly bring ultra-broadband access to customers by using the existing copper twisted pair wiring that is often found in apartment buildings. Without it, we'd have to drill holes and pull fiber into each apartment unit we serve, a time consuming and challenging process that can be frustrating for customers. Nokia's solution allows us to deliver new enhanced services without ever having to enter the place of residence."

Federico Guillén, president of Nokia's Fixed Networks Business Group, said: "It's no secret that multi-technology strategies which maximize the use of both fiber and copper are effective in helping operators quickly role out new ultra-broadband services. This is particularly true in some cases like inside an apartment building, where more traditional Fiber-to-the-Home strategies can be very challenging to deploy. With the advancements that have been made in today's copper technologies, operators can now offer fiber-like speeds to enhance the way customers experience their broadband services. As market leaders in copper and fiber technologies, Nokia has the experience it takes to deliver these multi-technology broadband networks."

Nokia is the industry leader in technology, with more than 40  individual customer trials completed and 10 customers commercially deploying around the world, including Openreach Chunghwa Telecom A1 Telekom Austria and Energia Communications .

With new technology innovations, such as XG-FAST, Nokia remains committed to providing operators with a wide range of copper technologies essential to meet growing end-customer demand for gigabit services.

Did you know:

  • Bell Labs' innovative vectoring algorithms help to eliminate crosstalk and make even faster.
  • Nokia leads in DSL innovation, holding world speed records with Bell Labs' XG-FAST technology, demonstrating speeds of 10Gbps on a single copper pair.
  •  Nokia is the global market leader in xDSL technology with a total of more than 330 million xDSL lines, 80 million VDSL lines and 30 million vectoring lines shipped to date.

ADTRAN Surpasses its 10 Millionth Vectoring Port Shipment

ADTRAN’s domain expertise and industry leadership in vectoring solutions enables network operators to ramp 100Mbps service offerings to meet market demands

HUNTSVILLE--(BUSINESS WIRE)--Mar. 14, 2017-- ADTRAN®, Inc., (NASDAQ:ADTN), a leading provider of next-generation open networking solutions, announced that it has shipped its 10 millionth vectoring port as network operators in the U.S. and Europe look to maximize any and all paths to ultra broadband service delivery. Crossing this milestone demonstrates how ADTRAN’s industry-leading access portfolio is having an immediate and long-term impact as networks scale and users demand increased capacity at work, home and play. ADTRAN’s market leadership has grown over the past four quarters as the company shipped now more DSL and VDSL2 vectoring ports in North America than all other vendors combined. VDSL2 vectoring is key to network operators’ broadband strategy to deliver 100Mbps services using their existing DSL infrastructure that may only provide 10Mbps service today. Ideal for urban deployments and multi-dwelling units, vectoring presents a scalable, highly leverageable approach to delivering ten times the DSL capacity, creating a truly immersive consumer experience that millennials and other tech-savvy consumers crave.

“To meet our customers’ broadband needs, we continue to innovate and provide higher speeds using both fiber and copper-based solutions. Having a proven technology that we can leverage with our current network infrastructure is ideal,” said Aamir Hussain, EVP and CTO for CenturyLink. “ADTRAN’s vectoring solutions help us maximize our network broadband speeds to meet the current and future needs of our customers.”

Vectoring boosts the installed network performance by increasing service speeds to 100Mbps using VDSL2 vectoring and to over 300Mbps using higher spectrum Super-Vectoring. More service providers are turning to this technology to sell high-speed services when time-to-market or economic hurdles prevent the deployment of new fiber. This network capability is becoming more critical as new guidelines in Europe and the U.S. change and become mandated for what bandwidth speeds constitute the definition of competitive broadband service.

“As regulatory commissions in the U.S. and Europe change the definition of broadband, vectoring technology is allowing carriers to achieve these higher speeds within their existing infrastructure. According to our research, VDSL2 vectoring shipments continue to accelerate, accounting for a growing portion of overall VDSL2 shipments each quarter,” said Teresa Mastrangelo, founder of Broadbandtrends. “Vectoring provides operators with the opportunity to offer FTTH-like speeds over copper lines, while providing the flexibility necessary to address the immediate time-to-market, competitive and regulatory challenges they currently confront.”

“ADTRAN’s vectoring solution is by far our fastest growing technology segment, shipping 10 million vectoring ports since introducing the solution to market and putting ADTRAN at the forefront of a technology that is quickly gaining worldwide adoption,” said Jay Wilson, senior vice president, technology and strategy for ADTRAN. “Service providers require the flexibility we provide to build the type of network that fits customers’ demands and business goals. By making it easier for service providers to leverage their current assets, ADTRAN ensures a smoother migration path from existing copper networks to full ultra broadband deployments across the globe.”
