TeliaSonera has deployed G.fast technology to a selection of end-users in Helsinki as it seeks to meet demand for video and content services.
The telco is conducting a trial using equipment from China's Huawei. It has live customers using G.fast in the Finnish capital, but it did not disclose how extensive the trial project is, nor if or when it plans to move to commercial rollout.
G.fast is a technology that enables telecoms operators to boost their existing copper infrastructure, particularly in places where they have rolled out fibre-to-the-cabinet (FTTC) and need a high-speed copper connection into the customer premises. G.fast enables speeds of up to 1 Gbps over copper, but only over a distance of around 250 metres. It is designed to be used in tandem with a vectoring solution to eliminate crosstalk.
The technology received first-stage approval from the ITU late last year and could be standardised as soon as April this year.
In a statement, Huawei said that the field trial with TeliaSonera demonstrates that G.fast can meet the demand for future broadband and video services, including 4K TV, which offers four times the picture resolution of HD TV and therefore requires more capacity.
However, the vendor did not share any specific results from the trial.
"The technology to deliver ultra-high-speed broadband connections over old copper lines makes it possible for us to improve the experience for more customers faster and thus make the most of our copper network," said Isto Pasanen, head of consumer services at TeliaSonera's networks business.
TeliaSonera is not the first European operator to trial G.fast.
In July Telekom Austria announced that it had conducted a trial of the technology alongside Alcatel-Lucent.
