New option where you have copper, digging fiber would be expensive, and you don't have line of sight for microwave. Sckipio's single port G.fast is an ideal solution if you need hundreds of megabits a few hundred meters from fiber. A telco engineer told me five months ago that is a common situation. He wanted a way to use a single line of G.fast. For a decade, people have been making connections like that with six and twelve lines of DSL, awkward and fairly expensive. Copper phone wires go almost everywhere and often you can find a fairly direct connection - especially if you are the phone company with access to the manholes. It's easy to imagine a small radio station with a dozen people on staff across a highway from fiber, or three homes about 200 meters beyond a telco GPON network. 

I live about 50 meters from Columbia's Engineering School, with probably a terabit of connectivity. There are 50 apartments in my building and 800-1000 apartments like mine within 200 meters. Most are owned by Columbia. Verizon can't deliver more than 6 megabits to any of us. It would be easy to deliver 500-800 megabits of G.fast to our building if you could find a simple wire run from Columbia, which may well be in place.

Connect that copper line to a G.fast unit in the basement, and everyone in the building could have several hundred megabits 95+% of the time. We could have 50/50 or close to 100/100 with cheap, quickly installed VDSL. (Fortunately, we have high speed cable. Most of the world doesn't.)  

I bet field engineers reading this can recall dozens of circumstances this would do the job.

SCKIPIO ANNOUNCES WORLD’S FIRST SINGLE PORT G.FAST DPU WITH DYNAMIC TIME ASSIGNMENT

Extends GPON networks by leveraging existing coax and copper wiring

Ramat Gan, Israel – October 11, 2016 – Sckipio Technologies, the leader in G.fast, announces the first single-port G.fast distribution point unit (DPU) reference design to provide up to 1Gbps of symmetrical broadband over existing coax and copper wiring. The solution acts like virtual fibre by extending GPON networks with twisted pair or coax within multi-dwelling units (MDUs) and single-family households (SFUs).

The new reference design leverages Sckipio’s breakthrough dynamic time assignment technology (DTA), which provides up to 1Gbps of broadband access in either direction. The solution also supports reverse power feeding from Microsemi to make it easy to implement in many environments including at the door, at the floor, in the basement or outside the residence.

Sckipio’s solution uses a very thin management layer for G.fast allowing operators to keep their existing GPON management layer and to extend it with a separate G.fast management layer. This speeds up the FTTH rollout by avoiding costly and time consuming IT integration of new management protocols into existing management frameworks.

The joint reference design was build in conjunction with Intel and Microsemi, offering OEMs the fastest path to deployable single-port DPUs. The solution will work within an existing Intel-based GPON management infrastructure.

“Sckipio is opening up an entirely new use-case for G.fast,” said Teresa Mastrangelo, Principal Analyst, Broadbandtrends. “By combining DTA and unmanaged G.fast, Sckipio makes it effortless to add G.fast to any GPON network.”

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
