Use more spectrum, get higher speeds at very short distances. They showed a prototype at BBWF they claimed would provide "3.8 Gbps @ 50 meters and 2.4Gbps @70 meters." Huawei's name for the next generation, 2-8 gigabit DSL is NG-fast. They brought a unit to BBWF and put out the press release with the information below. The speed is primarily coming by using 500 MHz of spectrum. Full duplex allows using the same spectrum for both upstream and down. The high speeds require significantly advanced processing power, raising challenging heat and space issues.

Nokia/Alcatel has been demonstrating their comparable technology, XG-FAST, at even higher speeds. It's good to see Nokia getting competition. I've asked Huawei for more technical details. I'd hope to learn more about the vectoring specifications, the chips they are using for processing, and the analog components. No word on when they expect to have units for testing, much less production. 

This is state of the art and beyond, so reserve your opinions until we get results from production equipment.

Huawei's NG-fast Prototype Debuts at BBWF 2016

 
 
10/19/2016
 

LONDON -- Huawei's NG-fast (next-generation G.fast) prototype debuted at the Broadband World Forum (BBWF) 2016. According to the test report from Huawei's FBB Innovation Lab, this prototype provides a bandwidth of 3.8 Gbps @ 50 meters and 2.4Gbps @70 meters over a single twisted pair. This development exemplifies Huawei's capability for continuous innovation in the DSL access field and also helps carriers worldwide further tap into the potential of their copper network resources.

As new services such as 8K and virtual reality (VR) video flourish, carriers require the following from their copper networks: ultra-high bandwidth, low latency, low cost, and ease of deployment. The maturity of G.fast in 2014 prompted Huawei to start researching NG-fast and consider it to be the cutting-edge technologies for the next-generation copper access field. This demonstration of the NG-fast prototype attracted considerable attention in the industry. The prototype extends the frequency band to 500 MHz and adopts full-duplex transmission, achieving a qualitative leap in transmission rate and greatly reducing transmission latency.

With the industry's largest-capacity vectoring system and its extensive experience in commercial application of G.fast, Huawei has accumulated a great number of crosstalk cancellation algorithms and advanced engineering capabilities. Highly concerned with the cost and deployment of NG-fast, Huawei has set up a team dedicated to NG-fast research and produced innovative results in terms of technical architecture.

Such results include the concept of virtual DSLAM. Since the digital signal processing module is moved up the network, a virtual DSLAM requires far less space and can therefore be deployed almost anywhere – for example, on a traditional node such as a cross-connection box or a weak-current well. It is predicted that the virtual DSLAM will be able to effectively support large-scale NG-fast rollout and solve related issues. In addition, moving up the digital signal processing module also simplifies the structure of the virtual DSLAM, removing the need for on-site maintenance and, thereby reduces the cost of maintenance.

"Relying on our technological accumulation in the superfast copper line field, Huawei continues to innovate in this area. The launch of the NG-fast prototype undoubtedly boosts carrier confidence in the reuse of existing copper line resources and quick construction of gigabit ultra-broadband networks," said Jeff Wang, President of the Huawei Access Network Product Line.

G.fast News
A remarkable 400 people attended the very strong Broadband Forum BASE events in Berlin and Las Vegas. Trevor confirmed BT would pass the million this year. Cioffi projected “Waveguide DSL” could carry 10 gigabits a kilometer as well as a terabit 100 meters. Werner sees a 4X improvement in upstream with cDTA. Much more in next issue.

Deutsche Wants a Gigabit, Finally Realizes 50 Meg Isn't Enough http://bit.ly/2zeZ5oZ
Deutsche Telekom is finally realizing that 50 megabit DSL won't make it against gigabit cable. VP Franz Seiser is blunt. "We must change radically, become disruptive and, above all, throw away things," he proclaims at BBWF. After years of DT insisting 50 megabits is plenty, we now hear "it is about Gigabit products" from DT's Robert Soukup.  
    A lucky building in Frankfurt will receive 500+ megabit service as ultra-conservative Deutsche Telekom experiments with G.fast. Soukup told BBWF, "We're going to have a field test in Frankfurt with G.fast and Fiber To The Building (FTTB.) We will know by the end of the year if this is the right way to go." Hint to Soukup: Yes it is. G.fast is working well at a dozen telcos I;ve talked to.
     The details are surprising. DT is going for CORD, Open Source, Calix, and Radisys. http://bit.ly/2zeZ5oZ

*** The new Telebyte Guide to Testing Gfast follows the Broadband Forum IR-337 Gfast test specification, the same used by the University of New Hampshire (UNH-IOL) for Gfast certification testing.

1.6 Gig in Sckipio-Calix Test http://bit.ly/Calix16
A telco tells me they are getting impressive early results from the Calix 48 port DSLAM with the new Sckipio 212 MHz chips. There still is work to do but this is encouraging. 
    Carriers want DSLAMs with more than 16 ports to reduce the deployment costs from the basement or larger field cabinets. Speed matters to the marketing side of the company; AT&T's CEO believes he must offer a true gigabit to match cable. (They've been getting ~750 megabits with first generation chips. http://bit.ly/Calix16

Reverse Power 4 Port DSLAM for Australia http://bit.ly/NetcommRP
Australia is connecting 1M homes to G.fast, some with a Netcomm distribution point mini-DSLAM. It's a small unit designed for pole or pit mounting. It's waterproof, pressure proof, and temperature resistant. Their matching home modem is bittorrent friendly, with two USB ports for a hard drive dedicated to sharing.
     A reverse power unit at the customer, the NDD-0100-01, can save the cost of bringing power to the DSLAM. They don't expect many orders until the second half of 2018, as nbn is waiting for the second generation chips. Netcomm demonstrated RP with BT Openreach in August. http://bit.ly/NetcommRP

Australia Makes it Official: G.fast to Million Plus http://bit.ly/GFAussie
No news here. In September, 2015, I reported Australia's nbn Going G.fast. This June. I reported the million home fiber to the curb (kerb?) was beginning. Unfortunately, they are no closer to figuring out where to find the needed $10B to $20B to cover the cost overruns. Instead, the parties are battling in Parliament about who is to blame. http://bit.ly/GFAussie

2 Bonded 212 Lines = 3 Gigabitshttp://bit.ly/twobonded
Sckipio at BBWF is demonstrating 3 gigabits down, nearly a gigabit up, over two phone lines, bonded. Twice the bandwidth (212 MHz instead of 106 MHz) times two lines is fast. Sckipio does great demos; at CES, they showed G.fast first generation chips delivering almost 1 gig upstream.
    “Sckipio is pushing Gfast to astonishing speeds with production silicon,” CEO David Baum proclaims. Calix is using the SCK23000 chipset in their 48 port gig+ DSLAM at the show. http://bit.ly/twobonded
