Usain bolt Fastest at 100 meters"G.fast can reach 400 meters, and for distances under 250 meters it is faster than the proposed new 35 MHz VDSL2 profile (“MDSL”)." A senior engineer writes. He corrected my comment, "100 meter G.fast doesn't go far enough." He added, "For distances under 250 meters it is faster than the proposed new 35 MHz VDSL2 profile." The speeds past 100 meters drop very rapidly but are still perhaps 100 megabits down at 400 meters.

Sckipio claims lab tests of G.fast at speeds produced 500Mbps for 200 meters and 200Mbps at 400 meters, (below) Sckipio, like many in G.fast, counts both upstream and downstream. No one does that in fiber or cable making this confusing for many.  Subtracting upstream would reduce Sckipio claims by 1/4th to 1/2 

With BT interested in 400 meter deployments, the industry is responding. "Gigabit DSL" makes great headlines but requires coming within 50 meters of most homes, an expensive proposition.

Many carriers are looking for a choice between the 100-200 megabits of DSL vectoring and the 300-700+ megabits of the G.fast standard. That's MDSL or Midi-DSL, currently an area of much research and many claims by the manufacturers. Huawei calls it SuperVector;  Adtran calls it "frequency-division vectoring"; Alcatel's name is name is Vplus. Vectored VDSL2 was designed for 100 megabits down for 700-1000 meters, one heckuva result for 10 years ago. Telcos desired more speed as they realized that cable was going to 400 megabits and over a gigabit. (I've been predicting gigabit cable since 2005 but it wasn't practical until a few years ago.) In fear, the telcos supported G.fast for maximum performance. 

G.fast is becoming real, with BT announcing a 4,000 home trial beginning this summer. 

  

Sckipio Makes G.fast Go Twice as Far

Makes New FCC Regulations More Practical

February 4, 2015, Ramat Gan, Israel – Sckipio Technologies, the leader in G.fast, today announced it has successfully demonstrated G.fast at speeds greater than 500Mbps for 200 meters – double the official ITU targets for this new broadband standard. In laboratory trials with multiple broadband access service providers globally, Sckipio also achieved more than 200Mbps at 400 meters, again doubling the target distance for the given rate. These important test results will help widen the potential footprint for G.fast and help telecommunications companies better address new FCC regulations now being proposed in the U.S.

“G.fast was optimized to deliver up to 1Gbps in short distances,” said David Baum, CEO of Sckipio Technologies. “Yet, we tuned our technology to allow telcos to reach more customers with higher performance from farther away.”

The U.S. government recently redefined broadband access as 25Mbps or greater – downgrading most xDSL subscribers to non-broadband status. While cable companies have access to technologies such as DOCSIS to achieve greater than 25Mbps performance, telcos have lacked affordable alternatives to fiber to the home (FTTH) and xDSL. That’s why the International Telecommunications Union (ITU-T) created a new standard called G.fast, which was approved in December 2014.

The Sckipio improvement of G.fast performance over distances such as 400 meters will open up more potential uses for G.fast in rural environments. It also will help in very dense environments like large cities where as many as 30% of all residences lack alternatives to cable operators.

The initial test results are preliminary and based upon lab evaluations over real binders.  Sckipio expects additional performance improvements as the solution is further optimized.

212 GHz and cDTA are soon shipping from Adtran. True gigabit is here. Sales takeoff is almost in sight, probably Q1 2018.
Australia confirms 1M, AT&T is ready to ramp, DT finally is moving. Omantel and Telkom South Africa are now on the map. Almost all telcos are now choosing G.fast for large buildings when they don't go FTTH. MNet Cologne and Chunghwa Taiwan have changed from fiber all the way to G.fast in the basement.
