By combining four ultra-broadband technologies, ADTRAN designed a gigabit-to-the-basement (GTTB) solution that extends gigabit services 650 meters from where fiber ends, empowering service providers to more rapidly and cost-effectively deliver high-speed Internet in dense urban environments.
Whereas fiber-to-the-distribution-point (FTTdp) or -building (FTTB) solutions usually add another 50 to 100 meters to fiber services, ADTRAN's GTTB offering means operators can more easily avoid expensive, time-consuming construction, said Kurt Raaflaub, head of strategic solutions marketing at ADTRAN, in an interview. That translates into implementations two to five times faster at about one tenth of the cost of FTTdp/B solutions, he said.
ADTRAN's GTTB solution incorporates technologies such as the vendor's second-generation SDX 2200 series of 212MHz, reverse-powered Gfast DPUs with bonded super-vectoring (VDSL2 35b) technology. Skip one of those elements and GTTB would not exist, Raaflaub noted.
"All these great innovations are coming in, we're just putting them in a bucket and stirring them around to make a really nice mix," he said. "Take any one of those innovations out and it just doesn't work. You have to have super vectoring. You have to have copper bonding. You have to have 212. You have to have reverse bonding."
And, if service providers add fiber at a later date, they can incorporate it into the existing GTTB solution, Raaflaub said.
Although ADTRAN declined to name any service providers currently using its GTTB offering, Raaflaub cited some "Central European" customers that are leveraging the Gfast-based solution's ability to use existing copper wire to provide customers with speedy broadband. ADTRAN customers in that region include Deutsche Telecom, which has publicly shared many of its pilots with ADTRAN involving vectoring, super vectoring and Gfast.

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
