How does NBN technology work?

Forget the Bronze Age, the Copper Age was where Australia’s Internet infrastructure had been stuck for the last couple of decades. Old tech like dial-up and ADSL used copper telephone lines to bring you your favourite memes, chain emails and Flash animations. However, the advent of the NBN means the Fibre-Optic Age is here. 

With improved cabling, faster Internet speeds are achievable — even as quick as 1,000Mbps. But there’s a catch. Getting everyone up to speed on fibre-optic NBN cables is a big task. That’s why NBN Co is taking a ‘multi-technology mix’ approach, using a range of existing and new technologies to upgrade Internet experiences across Australia. 

What are the different types of NBN connections? 

If you’re new to the whole NBN scene, wrapping your head around the different connection types can be tricky. That’s why we’ve made this handy cheat sheet for you — at a glance you’ll be able to tell your FTTPs from your FTTNs. We’ve also got some extra tidbits if you want to really impress your friends with your NBN knowledge or simply want to know what to expect when the NBN technician turns up on your doorstep. 

Connection Technology Used Typical Usage 
FTTP Full fibre-optic cable Areas with an existing fibre network 
HFC Mix of fibre and coaxial cable Areas with existing pay TV or cable networks 
FTTN Fibre to a local node, then copper to homes Areas with existing copper networks 
FTTC Fibre to a curb point, then copper Areas where fibre to the premises is not yet feasible 
FTTB Fibre to the building’s communications room, then copper Apartment buildings and offices 
Fixed Wireless Wireless technology Rural areas without cable infrastructure 
Sky Muster Satellite technology Remote areas without ground connectivity 

Fibre to the Premises (FTTP) 

FTTP is a fixed line connection that’s fibre all the way, meaning you could enjoy some of the fastest Internet around. Besides the fibre cabling, the only other equipment needed is an NBN connection box, NBN utility box, a power supply unit and your modem. The modem will come from your Internet Provider, while everything else NBN Co will provide and install. Once it’s all set up and connected, you’ll have Internet.  

Hybrid Fibre Coaxial (HFC) 

HFC is a fixed line connection that’s true to its name: it uses a mix of fibre-optic cables and coaxial cables (the kind of cables that pay TV networks use). To get you online, NBN Co will need to install an NBN connection box and NBN utility box. From there, you’ll just need to connect your modem to the connection box, then you should be up and running. 

Fibre to the Node (FTTN) 

The FTTN and other ‘fixed line’ connections below use copper cables (in addition to other technology) to get you Internet at home. Unfortunately, that means they can’t quite reach the same speeds as FTTP and HFC connections due to the limitations of copper cables. 

With FTTN, it’s a little like the NBN is shy about coming over to your place. It hangs out in a fibre node nearby, typically in a street cabinet. Your existing copper lines, though, extends out to it, delivering you that Internet goodness.  

Beyond making sure you’ve got a telephone wall socket and a VDSL2-compatible modem, you shouldn’t need any other special equipment to connect to the NBN. If you don’t have a wall socket, you’ll need to get a cabler in. When it comes to the modem, your Internet Provider should send you one.  

Fibre to the Curb (FTTC) 

FFTC is another shy fixed line connection. However, it has a little more nerve, bringing its fibre cable self to the curb near your home (a distribution point in a pit in your street). Then the copper lines save the day once more and connect your home to ensure you can enjoy the Internet.  

Covering that little extra distance using fibre cables means that FTTC is theoretically able to reach five times the max speeds of FTTN. It does mean you’ll need an NBN connection box though, but this plugs into an existing telephone wall socket rather than needing professional installation. Once you plug your modem into the connection box, you should be good to go. 

Fibre to the Building (FTTB) 

FTTB is a fixed line connection you’ll likely see in apartment blocks or multi-dwelling units. The fibre cable will run into the building and to the communications rooms. From there, existing Internet infrastructure connects each residence to the NBN. 

If you’ve got an FTTB connection, you won’t need a visit from the NBN fairy (or technician) either. You should just be able to go ahead and plug your VDSL2-compatible modem into the telephone socket and start checking your socials. 

Fixed Wireless 

Forget tangled wires, Fixed Wireless is, well, wireless. To a point anyway. An NBN connection box and outdoor antenna need to be installed at your place to receive the data transmission from nearby NBN towers. 

Sky Muster 

Sky Muster transmits your NBN access via satellites, beaming the Internet to your home. Rather than fibre cables and nodes, NBN Co will need to install a satellite dish, power pack, wall outlet and special NBN modem to get you connected.  

How will NBN technology change in the future? 

Back in the dinosaur dial-up days, the speeds the NBN can achieve were unthinkable. So, what will we think is quaint or outrageous when we look back at the NBN in 20 years? These are a few of our predictions for the NBN’s future:
