Australia’s nbn says it has achieved downstream speeds of 1 Gbps in trials for DOCSIS 3.1 on its Hybrid Fiber Coax (HFC) network (which previously served as Telstra’s cable TV network).

The lab trial conducted in Melbourne also delivered upstream speeds of 100 Mbps – more than double the current highest 40 Mbps upload speed available on HFC retail services.

Nbn will be one of the first operators outside of the US to commercially launch DOCSIS 3.1 technology as an upgrade path for the HFC network and able to deliver gigabit downstream wholesale speeds.

Nbn is planning further lab testing of DOCSIS 3.1 in August, followed by in-field trials in December, ahead of a potential commercial launch of DOCSIS 3.1 services sometime next year.

Bill Morrow, CEO at nbn, said the  early tests of DOCSIS 3.1 are “very exciting”, and that the technology will enable its HFC network to deliver FTTP-level broadband connectivity in Sydney, Melbourne, Brisbane, Adelaide, Perth and the Gold Coast.

“The best news is that we will be able to bring Gigabit broadband to these premises far more quickly, cost effectively and with less disruption to end users than alternate technologies in these busy urban areas,” he said.
