For the readiness of your address, you will also see what nbn connection type has been used at
your location. While they all connect to the same nbn infrastructure, how this happens, and
what this means for you, differs.
Fibre to the Premises (FTTP)
The is the purest form of connection, with the nbn optical fibre line running all the way to the
premises. An nbn connection box and power supply unit are usually installed inside the
premises and your modem connects to this. This type of connection supports all speed tiers
offered by nbn providers, up to a theoretical maximum speed of 1Gbps.
Fibre to the Node (FTTN)
This connection type combines optic fibre and existing copper infrastructure. The nbn optical
fibre network connects to a node that is installed outside the premises, with multiple nearby
premises all connecting to a single node. The connection between the node and the premises
uses existing copper cables, but always trying to keep the distance between premises and the
node as short as possible. Your modem connects to your existing phone socket or jack, and this
type of connection supports all speed tiers offered by nbn providers, up to a theoretical
maximum speed of 100Mbps.
Fibre to the Curb (FTTC)
Similar to FTTN, but with multiple premises connecting to a Distribution Point Unit (DPU)
installed in the street using existing copper cables. The DPU connects to the nearest fibre node
using optical fibre. A nbn connection box and power supply unit are usually installed inside the
premises and your modem connects to this. This type of connection supports all speed tiers
offered by nbn providers, up to a theoretical maximum speed of 500Mbps.
Fibre to the Building (FTTB)
As the name suggests, this connection type is reserved for building and multi-unit residential
apartments. A fibre node is installed in the building’s basement or communications room, with
optic fibre connecting this node to the nearest nbn exchange. Each unit in the building connects
to this fibre node using existing technology. This type of connection supports all speed tiers
offered by nbn providers, up to a theoretical maximum speed of 100Mbps.
Hybrid Fibre-Coaxial (HFC)
If you have Pay TV or cable TV installed, part of this infrastructure could be used to connect your
premises to the nearest fibre node using an HFC line. The node still connects to the nearest nbn
exchange using optical fibre. A nbn connection box and power supply unit are usually installed
inside the premises and your modem connects to this. This type of connection supports all
speed tiers offered by nbn providers, up to a theoretical maximum speed of 1Gbps.
Fixed Wireless
The above connection types are all referred to as Fixed Line Connections and are used
throughout Australia’s largest cities and some nearby towns. Outlying suburbs and regional
towns use Fixed Wireless technology. Optic fibre connects nearby transmission towers to the
nbn, and these towers transmit data wirelessly to connected premises. An outdoor antenna is
installed at the premises to both receive and send data to the nearby towers, with a nbn
connection box and power supply unit installed inside the premises and your modem
connecting to this. This type of connection supports all speed tiers offered by nbn providers, up
to a theoretical maximum speed of 75Mbps.
Sky Muster Satellite Service
Satellite connections to the nbn are used only for very remote premises, with a roof mounted
satellite dish sending and receiving data from orbiting satellites. While this does now make it
possible for properties that did not qualify for an ADSL connection to now connect to the nbn, it
is still more limited than other connection types, with theoretical maximum speeds of only up
to 25Mbps.
