FTTN - Computer Definition
or Fiber-To-The-Node) Also known as Fiber-To-The-Curb (FTTC).A hybrid broadband local loop configuration that involves optical fiber from the edge of the telco or CATV network to an intelligent node in the neighborhood, with one node serving perhaps many residences or small businesses. The few hundred meters or so of the local loop from the node to the premises generally is either unshielded twisted pair (UTP) in a telco application or coaxial cable (coax) in a CATV application, although some form of wireless technology is also possible.The fiber portion of a contemporary FTTN configuration generally conforms to one of the passive optical network (PON) standards. See also broadband, CATV, local loop, node, optical fiber, telco, and UTP.
(Fiber To The Neighborhood or Node) The installation of optical fiber to a junction box (node) in a neighborhood that serves a few hundred customers within a radius of about a mile. The connections from the node to the customer premises often uses DSL over existing telephone wires or coaxial cable (DOCSIS) from the cable company. FTTN Vs. FTTC If the radius of customers served by the node is less than a thousand feet, the service is typically called "fiber to the curb" (FTTC). See FTTx.
