What is Hybrid Fibre Coaxial (HFC) broadband?

Hybrid Fibre Coaxial (HFC) broadband is a classification for a type of broadband connection in Australia that uses pre-existing coaxial (pay TV) cabling to deliver the internet.

High-speed fibre connects from the closest Point of Interconnect (POI) to its nearest ‘Node’, which is a nearby connection hub that connects you and your neighbourhood to the larger broadband network. Data travels through the coaxial cabling underground (or, sometimes overhead) to reach an indoor wall socket at the user’s premises which connects to a Network Termination Device (NTD). From here, your modem/router connects to the NTD to access the world wide web.

From left to right, there is: 'Point of interconnect', 'NBN', 'Node', 'Coaxial' cable; which is shown leading into a house. Outside the house is 'NBN utility box', and inside the house is 'NBN connection box'.

Sometimes, a premises may be listed for HFC installation even when the house has never had pay TV installed. This is normal! HFC broadband is used in some areas where this type of cabling is commonplace, so it will be easy for a technician to install.

The maximum potential speeds for this type of connection are 1000mbps (megabits per second) when downloading, and 50mbps when uploading. There are many factors as to why a connection may be achieving lower speeds – for improving on slow speeds, check out some of our troubleshooting guides here.

Note: HFC connections must use an NTD (Network Termination Device). If you do not have one, please contact our team on 1300 880 905.
