nbn set for G.fast launch in 2018

Using G.fast technology will help nbn provide access to ultra-fast broadband speeds on our Fibre-to-the-Curb (FTTC) and Fibre-to-the-Building (FTTB) networks sooner and more cost effectively.

Our announcement that we will be launching G.fast technology in 2018 shows once again our commitment to delivering world-class, cutting-edge technology to Australians receiving services on the nbn™ broadband access network. By using a higher spectrum frequency of 212MHz, G.fast technology allows speeds of up to 1Gbps to be delivered on twisted-pair copper lines of up to 100 metres and can even deliver speeds of around 400Mbps on around 300 metres of copper, with further speed boosts likely as the technology is further developed. From an nbn point of view, G.fast gives us the opportunity to provide access to ultra-fast speeds on our FTTC or FTTB network at far less time and cost than delivering full Fibre-to-the-Premises (FTTP). By 2020, all of our FTTP end-user premises, as well as those receiving services via Hybrid Fibre-Coaxial (HFC), will already be able to receive Gigabit services – so G.fast will give us the capability to extend those ultra-fast speeds to our FTTC and FTTB networks.

Global momentum

Global telecom operators first began deploying G.fast technology last year with commercial launches from Swisscom in Switzerland with follow up launches this year by US giant AT&T and Taiwan’s Chunghwa Telecom, whilst UK operator BT is also deploying a trial G.fast pilot to one million premises, delivering speeds of 330Mbps. UK research firm Ovum forecasts that there will be nearly 30 million G.fast subscribers in the global market by 2021 as other telcos around the world – including nbn – use the technology to provide access to ultra-fast speeds without the cost and time of deploying full FTTP. From an nbn perspective, we know how time-consuming and expensive taking fibre all the way into an end-user premises can be, so for us to be able to move towards providing access to ultra-fast speeds over FTTC and FTTB networks is a win for both nbn and Australians who will be able to connect to ultra-fast speeds far more conveniently. Some of the connections on our FTTP network have cost well beyond $20,000 to connect because of the cost of running new fibre down lengthy driveways – but by using G.fast over an FTTC connection we can deliver ultra-fast speeds at a fraction of that cost.
