Telecom equipment vendor Adtran says it has developed broadband speeds close to 500Mbps over copper lines. Even though some vendors are looking at fiber optics, that is still too expensive and in some areas not feasible.

The company said it has developed what is calls FDV (Frequency Division Vectoring). This consists of two technologies: VDSL2 with vectoring and G.fast.

VDSL2 with vectoring, which improves speeds by reducing noise and can deliver up to 150Mbps, is currently being rolled out by operators, while G.fast, which is capable of 500Mbps, is still under development.

according to Adtran, FDV will make it easier for operators to roll out G.fast once it’s ready and expand where it can be used. The technology increases the bandwidth by using more spectrum. G.fast will use 106MHz of spectrum, which compares to the 17MHz or 30MHz used by VDSL2.

Expect it to roll out in 2015.
