The roll out of the National Broadband Network under the December 2013 strategic review has placed a greater emphasis on existing hybrid fibre coax plant being utilised within the national broadband infrastructure. 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.
Before this incorporation within the NBN, the cable networks of Telstra and Optus had both been upgraded with DOCSIS3.0 technology, with many nodes capable of delivering data at up to 100Mb/s while the remainder can deliver data at up to 30Mb/s. In international terms, the capabilities of HFC in Australia remain comparatively low, and there is considerable scope for improvement. In Europe, HFC networks commonly deliver data at up to 360MB/s, while some networks (such as Vodafone’s in Germany) deliver data at 400Mb/s.
Nbn completed trials of its HFC service in Redcliffe, Queensland, in February 2016 and planned to launch commercial services later in the year, with some 3.6 million premises expected to be serviced by the network. Nbn is also expected to operate services based on the DOCSIS3.1 during 2017, capable of delivering data at 1Gb/s. With the NBN being a hot-topic in the run up to the federal election, the opposition Labor party has declared that it would maintain the current plan of using HFC with DOCSIS3.1 in major metro areas.
In markets across Europe as well as in North America the key driver for deploying DOCSIS3.1 is the wave of new broadband and video competitors. Telcos as well as new operators such as Google Fiber are deploying 1Gb/s services based on FttH, and this is prompting cablecos to accelerate their DOCSIS3.1 deployment plans.
