Sckipio improves G.fast’s speed, reach and density

Sckipio is using this week’s Broadband World Forum event in London to highlight its latest G.fast activities 

Sckipio has enhanced the performance of its G.fast chipset, demonstrating 1 gigabit data rates over 300 meter of telephone wire. The G.fast broadband standard has been specified for 100 meters only. The Israeli start-up has also demonstrated 2 gigabit performance by bonding two telephone wires.

“Understand that G.fast is still immature,” says Michael Weissman, co-founder and vice president of marketing at Sckipio. “We have improved the performance of G.fast by 40 percent this summer because we haven’t had time to do the optimisation until now.”

The company also announced a 32-port distribution point unit (DPU), the aggregation unit that is fed via fibre and delivers G.fast to residences.

G.fast adds to the broadband options of the service providers

Feature: G.fast

Source: Alcatel-Lucent

Competition is commonly what motivates service providers to upgrade their access networks. And operators are being given every incentive to respond. Cable operators are offering faster broadband rates and then there are initiatives such as Google Fiber.

Internet giant Google is planning 1 Gigabit fibre rollouts in up to 34 US cities covering 9 metro areas. The initiative prompted AT&T to issue its own list of 21 cities it is considering to offer a 1 Gigabit fibre-to-the-home (FTTH) service.

VDSL2 vectoring explained

Several system vendors including Adtran, Alcatel-Lucent and ZTE have announced vectoring technology that boosts the performance of very-high-bit-rate digital subscriber line (VDSL2) broadband access technology. Vectoring is used to counter crosstalk - signal leakage between the telephony twisted wire pairs that curtails VDSL2's bit rate performance – as is now explained.

Technology briefing

There is a large uncertainty in the resulting VDSL2 bit rate for a given loop length. With vectoring this uncertainty is almost removed

ICT could reduce global carbon emissions by 15%

Briefing: Green ICT

Part 1: Standards and best practices

Keith Dickerson is chair of the International Telecommunication Union's (ITU) working party on information and communications technology (ICT) and climate change.

In a Q&A with Gazettabyte, he discusses how ICT can help reduce emissions in other industries, where the power hot spots are in the network and what the ITU is doing.

"If you benchmark base stations across different countries and different operators, there is a 5:1 difference in their energy consumption"

DSL: Will phantom channels become real deployments?

Alcatel-Lucent’s Bell Labs has announced it has achieved a data rate of 300 megabits-per-second (Mbps) over 400m using digital subscriber line (DSL) technology. 

Alcatel-Lucent is promoting its DSL Phantom Mode technology as a complement to fibre-to-the-x (FTTx) technology. Operators can use the technology to continue to extend services offerings to existing DSL subscribers as they roll out FTTx over the next decade or more.

But one analyst believes the technology could take years to commercialise and questions whether the announcement is not sending a wrong message to the industry by providing an alternative to fibre.

“The investment required to upgrade DSL is quite small”
