NBN Connection Types

• Fibre to the Curb (FTTC)

  • Fibre optic cable runs closer to the premises, typically to a telecommunications pit on the street, with copper wiring connecting the final distance.

  • Faster and more reliable than FTTN due to shorter copper connections.

NBN Connection Device:
A small modem-like device provided by NBN works as an interface inside the premises to manage the signal over the copper line. It enables a VDSL2 signal to communicate with NBN equipment in the pit (where fibre ends and copper begins).

• Fibre to the Building (FTTB)

  • Common in multi-dwelling units (e.g., apartments).

  • Fibre optic cable runs to a shared point in the building, and internal wiring distributes the connection to individual units.

  • Similar to FTTN: No dedicated NBN-supplied device at the premises.

Requires a VDSL2-compatible modem-router, usually supplied by your ISP.

• Hybrid Fibre-Coaxial (HFC)

  • Uses existing pay-TV coaxial cable networks combined with fibre optic infrastructure.

  • Widely used in urban areas and supports high speeds.

  • NBN Connection Box:
    A modem-like device provided by NBN Co that connects to the coaxial cable and outputs an Ethernet connection for your router.

• Fibre to the Premises (FTTP)

  • A fiber optic cable runs directly to the premises.

  • Offers the highest speeds and reliability among all NBN technologies.

  • Network Termination Device (NTD):
    A wall-mounted device inside the premises where the fibre optic cable terminates. It provides Ethernet ports to connect to your router.

  • Optional Battery Backup Unit (for older installations):
    Ensures phone service during a power outage (being phased out).

 

• Fixed Wireless

  • Internet is delivered via radio signals from a tower to a rooftop antenna at the premises.

  • Speed and reliability can be affected by distance from the tower, weather, and obstructions.

  • Outdoor Antenna (Fixed Wireless Dish):
    Installed on the roof or an external wall, this connects to the NBN wireless tower.

  • NBN Connection Box:
    Installed inside the premises, it connects to the antenna and provides an Ethernet port for your router.
