Deutsche Telekom has concluded a laboratory trial of Alcatel-Lucent’s XG-FAST technology as it looks to add more options to its broadband toolkit.
The trial, which took place at DT’s cable laboratory in Darmstadt, generated data throughput speeds of more than 10 Gbps.
Nokia-owned A-L first unveiled the tech, which is an extension of traditional G.Fast, in July 2014.
The company said XG-FAST remained “in the early stages of lab testing”, but had exceeded expectations thus far.
DT is already using VDSL2 Vectoring tech to sweat its copper network.
This approach continues to divide opinion, with rivals accusing DT and other incumbents of taking a short-term view with this strategy.
DT’s Chief Technology Officer Bruno Jacobfeuerborn said: “[XG-FAST] will provide another technology option which could enable us to offer high-speed connectivity to our customers quickly and cost-effectively, and at the same time, move our fibre infrastructure closer to our customers."
Federico Guillén, President of Fixed Networks at Nokia, added: "The XG-FAST trial with Deutsche Telekom represents an important milestone in our ongoing efforts to extend the potential of copper for delivering ultra-fast speeds, while also bringing fiber closer to residential and business users."
Telekom Austria is set to launch G.Fast services, using A-L tech, this year.
Last November, the vendor’s research arm revealed it was testing a new optical networking technology that offers Petabit-per-second capacity.
