Australia - National Broadband Network - HFC Networks

Australia - National Broadband Network - HFC Networks

The HFC networks of Telstra and Optus's are being deployed as part of the NBN, so reducing the overall cost of the project's rollout. However, nbn's Corporate Plan for 2017 envisages greater use of FTTN in HFC areas, given the mounting cost of connecting premises with HFC.

NBN expects to be one of first operators outside of the US to commercially launch DOCSIS 3.1 technology as an upgrade path for the HFC network.

The DOCSIS 3.1 standard, could vastly increase the speed of that HFC network footprint and at a much lower capital cost than deploying FTTP.

Nbn is expected to operate services based on the DOCSIS3.1 at the end of 2018, capable of delivering data at 1Gb/s. It is also actively looking at other cable networking advances such as full-duplex DOCSIS technology, which is capable of 10Gbps symmetrical speeds.

The nbn has confirmed Fibre-to-the-Distribution-Point (FTTdp), also known as Fibre-to-the-curb, would be deployed to a potential footprint of up to 700,000 premises across the country. The nbn is abandoning plans to reuse existing Optus HFC assets, with the exception of the already launched network in Redcliffe, Queensland.

The expanded FTTC footprint fills the void left by NBN's decision not to use the Optus cable assets, although it will still be using Telstra's more extensive HFC network as planned. NBN is however still aiming for an HFC footprint of between 2.5 and 3.2 million premises by 2020, using the Telstra assets.
