Deutsche Telekom and ADTRAN are lab testing the next-generation G.fast standard 212Mhz and coordinated dynamic time allocation (cDTA) so the German service provider can evaluate its ability to use existing cable and phone infrastructure to deliver ultra-fast and gigabit services.
By using current cabling, DT can rapidly and affordably accelerate service deployment with minimal disruption.
"DT, for a long time now, has been an advocate of using their own built-in infrastructure and being very, very targeted with fiber overbuild and things like that. They've shown, going back several years ago with vectoring in our studies, 330 can connect a home and deliver 100 megabits whereas it's north of 1,000 for fiber to the home," Kurt Raaflaub, global marketing manager at ADTRAN, told UBB2020. "If I can cover more homes for the same amount of money, that's what I want to do."
ADTRAN has already proven the new 212MHz G.fast standard, which doubles usable spectrum, allowing operators to provide ultra-broadband speeds via one copper pair. By combining it with cDTA, speeds are even more rapid, enhancing G.fast upstream performance four- or five-fold, according to the vendor. It accomplishes this by dynamically balancing upstream and downstream capacity in real time to meet individual residential users' needs and extends usage to current phone wiring, in place at most existing homes and businesses.
In the lab tests, DT and ADTRAN expect to determine how far the combined technologies reach, whether it's a kilometer or less, Raaflaub said. But regardless of distance, G.fast implementations are more cost-effective, in part because they are forward-compatible with fiber-to-the-home (FTTH), he said.
"Once this gets proved out -- whether it's 30% or 40% or 50% of their subscribers that will be able to get this service -- they'll be able to get this service almost instantaneously, whereas if it was fiber, having to wait for neighborhood-by-neighborhood," added Raaflaub. "It has very minor construction and it's available."
In a flurry of activity throughout the week, Donald (DJ) LaVoy, Deputy Under Secretary for Rural Development at the US Department of Agriculture, and his team spent about $145.8 million in the non-urban or suburban areas of seven states.
Calix reported revenue of $120.19 million – up 4% – in Q4 2019, putting a bounce in the step of company president and CEO Carl Russo and a shine to Calix's ongoing transition from hardware vendor to a provider of platforms enabled by cloud, APIs and subscriber experience.
Looking to curtail e-waste and improve the bottom line, BT will require customers to return routers and set-top boxes, although subscribers will not have to pay a fee when they receive regular broadband equipment.
Deploying DOCSIS 3.1 across its entire footprint gave Rogers Communications the ability to offer speeds of up to 1 Gbit/s,
contributing to a broadband segement that generated about 60% of the Canadian operator's $3.05 billion (US) in Q4 cable earnings.
Over the next two years, approximately 60% of service providers (both large and small) will adopt virtualization on a wide scale across their networks, according to the latest survey report from Ovum. Why are providers making these moves? Is there an easy way to start?
Learn how and why service providers are using virtualization to transform their networks. This webinar will look at how providers are leveraging virtualization to create more flexible and agile networks while also providing a better customer experience. Expert speakers from netElastic and Heavy Reading will address the industry drivers for network virtualization, the benefits that can be realized, the challenges to face and the results of virtualization being achieved by providers today.
Key topics will include:
Current network infrastructure and the move to virtualization
Benefits and challenges of network virtualization
How providers can get started
Service provider success stories: the decision to virtualize, the solution, and results
