ADTRAN Aids NBN Distribution
ADTRAN, a leading provider of next-generation open networking solutions, has announced its gigabit-capable 2nd generation G.fast Distribution Point Units (DPUs) will be installed underground throughout Australia as NBN Co begins the next phase of future-proofing the country’s national broadband access network (nbn).
ADTRAN has shipped hundreds of thousands of the most advanced generation of G.fast ports for this project. G.fast is a fibre service extension technology which uses existing wired infrastructure.
The first G.fast DPUs are being installed in the Sydney suburb of Rockdale, where the newest phase of the wholesale nbn is being built out by 2020. This is the first network in the world to deliver broadband via in-ground G.fast DPUs, according to NBN Chief Network Engineering Officer Peter Ryan.
“ADTRAN is a valued strategic partner for nbn and has played a key role helping nbn meet our deployment goals to evolve our network,” Ryan said. “I am very pleased that we are taking this next step together on our journey of delivering cutting-edge technology to Australians with our first deployment of ADTRAN G.fast technology onto the nbn FTTC network. Having this technology in the ground today gives us additional flexibility to meet end-user demand as it evolves.”
ADTRAN was among the first to deliver G.fast solutions that conform with Amendment 3 of the ITU-T G.fast standard, which doubles the usable spectrum from 106 MHz to 212 MHz and reduces the power consumption to enable convenient and cost effective reverse power feeding. With Amendment 3, G.fast is now capable of providing an aggregated bandwidth of 2 Gbps, delivering fibre-like speeds for applications which require leveraging the existing phone or cable television wiring infrastructure. The increased capacity also helps operators with additional deployment flexibility, as for the first time G.fast-based services can be delivered to locations where these need to coexist with existing VDSL2 services while still maintaining the ability to deliver symmetric Gigabit speeds.
