Next-generation broadband technology to deliver ultra-fast speeds

Jun 26, 2018

nbn, the company building Australia’s broadband network, announced today that it will launch next-generation broadband technology G.fast on the nbn™ broadband access network in 2018 paving the way for ultra-fast speeds over copper lines.

Bringing G.fast technology into our Multi Technology Model (MTM) will allow nbn to enable ultra-fast speeds to end-users on our Fibre-to-the-Building (FTTB) and Fibre-to-the-Curb (FTTC) networks where those speeds are required.

G.fast takes broadband speeds over copper lines past the current 100Mbps levels delivered by VDSL technology to delivering speeds of up to 1Gbps over copper lines by using higher frequencies of either 106MHz or 212MHz – compared to just 17MHz on VDSL.

Global operators including AT&T in the US, BT in the UK, Swisscom and Taiwan’s Chunghwa Telecom have already launched the technology to end-users.

nbn has previously trialled G.fast technology in October 2015 – achieving speeds of 600Mbps on a 20 year-old stretch of 100 metre copper cabling and will conduct further testing before launch.

G.fast technology will be supplied to nbn by our three existing fixed-broadand suppliers Nokia, Adtran and Netcomm.

JB Rousselot, Chief Strategy Officer of nbn said:

“Bringing G.fast technology to the nbn™ access network in 2018 again shows our commitment to being at the cutting edge of emerging technologies.

“Delivering G.fast to our FTTC and FTTB end-users will allow us to bring them ultra-fast services faster and more cost effectively than if we had to deliver them a full Fibre-to-the-Premises connection.

“Our FTTP end-users can already access Gigabit services and DOCSIS 3.1 will supply Gigabit services to our HFC end-users – bringing G.fast on-board opens the way for Gigabit speeds to our FTTN user-base too.”
