so what is HFC?
Prior to becoming nbn-ready, every address in the country is mapped by the nbn™ to determine the type of network technology used to service your address, with each technology being installed in its own unique way.
There is currently a mixture of seven core technolgy types that are used to install the nbn™ and HFC (short for Hybrid Fibre-Coaxial) is one of these.
When a home is connected using HFC technology, fibre leads to a cabinet (referred to as a node) near your home. Existing ‘pay TV’ coaxial cabling is then used to connect the node to your premise which leads to a wall socket inside your home.
excuse us while we get technical for a second
Get ready because things are about to get a little complicated.
The nbn has Points on Interconnect (POIs) around the country that connect to the wider internet. These tend to be located in the old telephone exchange building in each suburb. From these POIs a fibre optic cable connects to nbn nodes (purpose-built street cabinets) which are closer to your house - a coaxial cable connects the node to your house.
For people who already have ‘pay TV’ or cable network this existing cable will replace the coaxial cable that runs from the fibre node to your house
