Fiber to the Home (FTTH) is an internet fixed access network connection technology that uses optical fibers from a central point to transmit data to and from devices located at homes. Once at the subscriber’s living or working space, the signal may be conveyed throughout the space using any means, including copper twisted pair, coaxial cable, wireless, WiFi or optical fiber. Passive Optical Networks (PON) and point-to-point Ethernet are architectures that can deliver services such as voice, video and data over FTTH networks directly from an operator’s central office or an edge location.
The broader FTTx broadband network architecture uses optical fiber to provide all, or part of the local loop used for last mile telecommunications. As fiber optic cables can carry much more data than traditional copper cables, especially over long distances, copper telephone networks built in the 20th century are now being replaced by fiber and point to multi-point PON technologies such as XGS-PON (50G/100G PON in the future) and point-to-point Active Ethernet. XGS-PON uses a single strand fiber network that reaches from the access concentrator at a service provider site (an Optical Line Terminal or “OLT”) to each subscriber side demarcation device (called an Optical Network Terminal or “ONT”).
