In fiber-to-the-premises systems, the signal is transmitted to the customer premises using [fiber optic](https://en.wikipedia.org/wiki/Fiber_optic "Fiber optic") technologies. Unlike many conventional telephone technologies, this does not provide power for premises equipment, nor is it suitable for direct connection to customer equipment. An **optical network terminal** (**ONT**, an [ITU-T](https://en.wikipedia.org/wiki/ITU-T "ITU-T") term), also known as an **optical network unit** (**ONU**, an [IEEE](https://en.wikipedia.org/wiki/IEEE "IEEE") term), is used to terminate the fiber optic line, [demultiplex](https://en.wikipedia.org/wiki/Multiplexing "Multiplexing") the signal into its component parts (voice [telephone](https://en.wikipedia.org/wiki/Telephone "Telephone"), [television](https://en.wikipedia.org/wiki/Television "Television"), and [Internet access](https://en.wikipedia.org/wiki/Internet_access "Internet access")), and provide power to customer telephones. As the ONT must derive its power from the customer premises electrical supply, many ONTs have the option for a [battery](https://en.wikipedia.org/wiki/Battery_(electricity) "Battery (electricity)") backup in order to maintain service in the event of a [power outage](https://en.wikipedia.org/wiki/Power_outage "Power outage").[[2]](https://en.wikipedia.org/wiki/Network_interface_device#cite_note-whatont-2) These terminals are used in both [active optical networks](https://en.wikipedia.org/wiki/Active_optical_network "Active optical network") and [passive optical networks](https://en.wikipedia.org/wiki/Passive_optical_network "Passive optical network").

In May 2016, Ting Internet launched the _Bring Your Own Router_ option, allowing customers to use Ting's [optical network terminal](https://en.wikipedia.org/wiki/Optical_network_terminal "Optical network terminal") at no additional cost, while pairing it with their own third party router
