aetheaAethra_videoDemo'd live at BBWF. Great Britain has 4,000,000 "distribution points," simple copper boxes generally without power. Bringing electricity to each box could double the cost of G.fast deployment, which is targeted at $100-250 home. Add monthly charges as well..

  To many telcos, the biggest advantage of G.fast is "parasitic power." The G.fast gear gets power from the customer gateway, not from the telco system. Instead of running a powerline to each box - often very expensive - the G.fast DSLAM draws power from each user's modem. That allows telcos to pop mini-DSLAMs on poles, in small underground spaces .... 

   The standards committee was confident parasitic power would work well. 

Power over Ethernet already does something similar. Aethra tested a single line VDSL unit back in 2012 with Lantiq. But Stefano Wosz in May pointed to problems that still needed to be solved. 

   What would happen when several users shut off  their modem? Can it handle the power surge when the phone is picked up? Will the customers accept the cost, probably $5-$15 per year? Will modems and DSLAMs all be interoperable?

   Yet one more obstacle to deploying G.fast by the millions.

   Seeing is believing. Here's a video of the demo. Aethra also has a short animation. PR below.

Aethra Telecommunications in Cooperation With ADTRAN Demonstrates the First Reverse Powered G.Fast Multi Port FTTdp System at Broadband World Forum

ANCONAItalyOctober 20, 2014 /PRNewswire/ --

Aethra Telecommunications and ADTRAN will demonstrate the first G.Fast Reverse Powered Fiber-to-the-Distribution-Point multi-port systems at Broadband World Forum 2014. ADTRAN will demonstrate one of its 500G series G.fast Distribution Point Unit (DPU) systems featuring the Aethra Telecommunications patent pending Reverse Power Sharing technology. This will allow operators the possibility to fully rely on the benefits of the Fiber-to-the-Distribution-Point (FTTdp) architecture with Reverse Power Feeding.

The Aethra Telecommunications Reverse Power Sharing technology is the result of Aethra Telecommunications pioneering experience on the Fiber-to-the-Distribution-Point architectures and Reverse Power Feeding technology:

  • ultra compact size design, with minimized space occupation of the powering subsystem
  • full G.Fast fiber like gigabit speeds, with zero impact of reverse powering on G.Fast performances
  • perfect power balancing between the users "at-DPU-side", regardless of the distance between the user and the DPU
  • optimized power efficiency, in order to offer the possibility to still be able to power the entire DPU with just one RPF
  • total separation and independence of each one of the lines
  • full self install system according to the FTTdp paradigm and safety regulations in the home of the customer
  • digital monitoring and management of the line status

An ADTRAN 500G series G.fast DPU and the Aethra Telecommunications RPS8 Reverse Power Sharing modules will be demoed at the Amsterdam Broadband World Forum 2014 Oct 21-23 at ADTRAN stand E30 and Aethra Telecommunications stand G50.

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
