Dubbed XG.fast, the new technology could be used to massively extend the life of existing copper wireline networks, offering telecom companies an alternative to laying costly fiber-optic networks to billions of homes that already have a telephone line — but more importantly, it might mean you finally get a serious upgrade from your ~10Mbps ADSL or ~50Mbps VDSL connection.

Bell Labs, now an R&D division of global telecoms giant Alcatel-Lucent, developed XG.fast as an extension of G.fast. G.fast is the successor to VDSL2 — the technology that is used by most FTTC (fiber-to-the-cabinet) installations around the world. Paired with FTTC, VDSL2 offers speeds of up to 150Mbps, G.fast is up to around 1.25Gbps — and XG.fast is from 2Gbps all the way up to 10Gbps ... read more
