Understanding NBN connection

Internet for your home or office router usually uses one of three types of termination.

Our choices in Australia with NBN have been mostly FTTN (fiber to the node) or FTTC (fiber to the curb). These connection types require a conversion to another media to your premises; either HFC (high frequency cable) or a copper RJ11 (the old POTS phone lines you’re probably use to). These connection types have big speed limits, due to the change in cable, usually maxing out at 100-250Mbps.

Less common  FTTP (fiber to the premises) is by far the best connection type available. Over 1 Gigabit (1000Mbps) is possible with this type of connection.

NBN FTTB

FTTN – Fibre to the node.

This delivery method uses your existing copper phone line to connect to a “node” usually down your street.

Pros: No intervention to property required. Cost-effective.

Cons: Speeds are very limited and more prone to connection issues. Usually 50-100Mbps is the maximum download speed.

FTTC – Fibre to the curb.

This brings the fibre a bit closer to you – to the curb of the street outside your premises. In this case, a HFC (coaxial) cable can be used.

Pros: A faster connection (250Mbps) is possible

Cons: Speed is limited. Some work required installing a cable and NTD (pictured) required.

FTTP – Fibre to the premises.

This is the best type of broadband connection.

Pros: Speeds up to and over 1000Mbps are possible. Least possibility of drop-outs.

Cons: Harder to install into older apartment buildings and houses than the other options.
