What is an ONT and where should I install it?

An ONT is an Optical Network Terminal. This device connects the fibre that has been wired to the outside of your house, to your modem.

The ONT is a small white plastic box (180mm x50mm x 120mm) that will be placed on your internal wall. 

It’s important that you think about where the ONT is placed before our technician arrives for your 'Agree' appointment as this can affect your broadband experience. Your modem will plug into your ONT so it should ideally be:

  • close to a power socket (the ONT is powered by a 12v adapter)
  • where you’re using the internet the most.
  • centrally located in your home if possible as that’s how your wifi works best
  • close to data-hungry devices like televisions, stereos and home servers.
