Fiber to the home (FTTH), also called “fiber to the premises” (FTTP), is the installation and use of optical fiber from a central point directly to individual buildings such as residences, apartment buildings and businesses to provide unprecedented high-speed Internet access.
In a fiber optic network there are two basic elements: An Optical Line Terminal (OTL) located at the ISP side and an Optical Network Unit (ONU) placed at the customer’s premises. The connection between these two elements is made with both optical and non-optical equipment and components.
