Optical network terminals

An optical network terminal mounted to the outside of a building, with the cover open

In fiber-to-the-premises systems, the signal is transmitted to the customer premises using 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 term), also known as an optical network unit (ONU, an IEEE term), is used to terminate the fiber optic line, demultiplex the signal into its component parts (voice telephonetelevision, and 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 backup in order to maintain service in the event of a power outage.[2] These terminals are used in both active optical networks and passive optical networks.

In May 2016, Ting Internet launched the Bring Your Own Router option, allowing customers to use Ting's optical network terminal at no additional cost, while pairing it with their own third party router
