Sckipio-24-ports

Supporting 30A should win Japanese & Korean market. The biggest problem for most telcos deploying DSL is that until now, no one made a DPU with more than 16 ports. HFR of Korea has the first 24 port DPU and a giant customer ready to go. $15B SK Telecom is Korea's largest wireless carrier and #2 in fixed. There are 9M apartments in Korea served with VDSL and copper LAN, most running at 100 megabits.

Korea Telecom is actively deploying GIGA Wire, their version of G.hn, for higher speeds. They intend to upgrade 95% of those units by the end of 2017. SK needs to respond quickly. Japan is similar; millions of their "fiber" lines are fiber to the basement + VDSL. Korea and Japan used an advanced version of VDSL, using 30 MHz rather than the 17 MHz common elsewhere. Ikanos, now gone, had long been the preferred vendor. Sckipio is first with G.fast chips designed to work with VDSL 30a. 

Curtis Frankenfeld of Century recently told me, "I would like G.fast to support a larger vectoring group than the current 16 ports." 

For now, Century is only using G.fast in smaller buildings. They want to avoid the binder management challenges in bigger buildings. Many buildings have far more than 16 apartments, with wires in the same bundle.

To get high speeds, all the wires in the bundle have to be "vectored" to reduce noise. At G.fast speeds of 500 megabits and more, that's been a challenge. Some vendors promise to reach 48 or 96 ports with an external vectoring unit. It doesn't look like they will be available in Q4, the original roadmap.

HFR and Sckipio Announce World’s First 24-Port G.fast DPU

Solution targets South Korea, Japan and other Asian markets

Ramat Gan, Israel – October 11, 2016 – Sckipio Technologies and South Korean network infrastructure equipment maker HFR, Inc. announce the world’s first G.fast distribution point unit (DPU) that supports up to 24 subscribers in a single DPU. HFR’s solution leverages Sckipio’s award-winning G.fast technology and internal distributed vectoring capability to deliver the highest performance available on the market today.

“G.fast is a global technology, and Sckipio is surely the market leader,” said a spokesperson from HFR. “Together we are developing solutions that will transform the South Korean, Japanese and other large Asian markets by upgrading the old VDSL2 infrastructure to ultrafast broadband using G.fast.”

The HFR solution is optimized to deliver up to 500Mbps per subscriber while co-existing with 30a profile VDSL customers and utilizes Sckipio’s chipsets to achieve unsurpassed G.fast port density.

In June 2016, SK Broadband President Yin-Chan Lee publicly announced the intention to provide gigabit Ethernet speeds of up to 500Mbps with two strands (one pair) of existing copper telephone lines in old apartments via G.fast. This was in response to the certification of G.fast by the national technical standard established by the RRA, the South Korean National Radio Research Agency.

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

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
