A study group meeting this week expects its work on G.fast and VDSL2 standards will result in the availability of gigabit-speed G.fast solutions before year-end.
The ITU-T Q4/15 Group, which focuses on copper access technology, is meeting at ADTRAN headquarters in Huntsville, Ala. The group is part of the International Telecommunications Union - Telecom standards body. Attendees such as AT&T, BT and
Deutsche Telekom are scheduled to address accelerating new G.fast features that achieve more symmetric service rates, higher service rates and adaptation for delay critical applications.
Broadband technology advances already have narrowed the gap between available features in fiber and in copper infrastructure, said Tom Starr, chairman of ITU-T WP1/15 and lead MTS at
AT&T, in a statement. More demand for network broadband speed, along with continuous development of vectoring technology, generate future opportunities for both fiber and copper-based solutions, he noted.
"This week we will progress these opportunities so that we can bring these next-generation technologies to life quickly," said Starr.
Digging in to goals
The group is trying to smooth out and work through 212-megahertz spectrum for G.fast, which today uses 106Mhz, and dynamic time slot allocation, said Kurt Raaflaub, head of global product marketing at ADTRAN in an interview with UBB2020. Once participants realize these goals, then G.fast speeds will double from an optimal, current speed of 500Mbps to 1 gigabyte, he said.
"When you get these two capabilities that we're working out right here… Working together to get 212Mbps, double the spectrum, double the capacity and getting collective, coordinated dynamic time slot allocation, gigabit's an absolute reality," said Raaflaub.
And since G.fast reuses existing infrastructure, such as twisted pair, implementation of high-speed broadband is faster and more cost-effective than alternatives like DOCSIS 3.1, he said.
That is the absolutely crux and value proposition of G.fast: You get to use existing infrastructure, whether it's twisted pairs going into each home to deliver a high-performance, high-bandwidth service or twisted pairs that are all over an apartment building or multi-dwelling unit," Raaflaub added.
After suffering many quarters of financial and broadband subscriber losses, Frontier Communications' bond owners are ready for dramatic change – including a replacement for CEO Dan McCarthy (pictured), Bloomberg reports today, citing several sources.
Verizon and Calix bonded four wavelengths in the lab, bringing Verizon closer to its goal of one unified network for multiple services, says Kevin Smith, vice president of network planning at Verizon, during Calix ConneXions 2019 in Las Vegas.
Calix must overcome ties to its hardware-based past and return to positive earnings, something CEO Carl Russo predicts will happen soon -- pointing to the vendor's flat Q3 earnings and uptick in Verizon orders as positive financial indicators.
The ongoing debate around GPON vs EPON can get as heated as discussions around politics and religion, but both technologies offer some advantages over the other depending on the needs your network is servicing.
In this webinar, we will focus on the facts around the GPON vs EPON debate and how that technological decision is almost always made based on factors outside the technology itself.
In this insightful Light Reading radio show, Kurt Raaflaub, Head of Strategic Solutions Marketing, will outline the key service provider challenges, deployment considerations, next-gen Gigabit technologies, and service models to win market share in the rapidly growing MDU market.
