NBN Co is exploring the development of new devices that will let it fuse Australia's existing copper infrastructure onto its HFC cable footprint and backhaul, the company has revealed.

The devices would essentially allow NBN Co to use its cable infrastructure to provide existing copper lead-ins with enough bandwidth to achieve vectored VDSL2 speeds. Vectored VDSL2 is a newer generation copper-based broadband technology capable of speeds up to 100Mbps over distances of half-a-kilometre.

At a Nokia event hosted at NBN's offices in Sydney last week, Fairfax Media asked NBN Co chief technology officer Dennis Steiger about the feasibility of such an approach to serving broadband to premises within the cable footprint.

"I think it's a brilliant idea," Steiger said, before explaining that NBN Co's plans to implement it were already in development.
