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.
County Broadband, 10-year-old former WISP that focused on fixed wireless, now concentrates solely on gigabit fiber, courtesy of a £46 million infusion from Aviva Investors – and the financial firm's desire to find a long-term investment vehicle to fund clients' pensions.
On July 12, the FCC said it will discuss one-touch make-ready at its August general meeting. That same day, Clearfield announced general availability of a common fiber distribution panel designed for use in every fiber deployment.
We will explore several fiber network environments, common vulnerabilities, and the business impact of failures. Fiber networks are typically a combination of owned and leased fiber. Learn how to reduce MTTR by up to 60% when an event occurs and how to detect degradation before it generates a service impact. Fiber monitoring of leased fiber helps ensure that the responsible party is dispatched for repair and SLAs can be managed. We will discuss both in service and out of service monitoring. Learn about the opportunities to improve business results in the following environments:
Hyperscale datacenters- the business need for near 100% uptime
5G small cell combined with leased fiber - ensuring the SLA for leased fiber
Long haul and Metro dark and lit fiber monitoring - reducing MTTR and preventing damage
FTTX construction and service activation in the access or MSO network - accelerating time to revenue
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.
