Fiber to the node (FTTN or FTTn (also known as fiber-to-the-neighborhood or fiber-to-the-cabinet (FTTCab)) is

a high-capacity bandwidth approach that uses both fiber and copper wires. Optical fiber is used from the core of the telco or CATV network to an intelligent node in the neighborhood where copper wire is used for the connection to the end-user, with one node serving perhaps many residences or small businesses. The few 100 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 an HFC application, although some form of wireless technology is also possible.[1]


"FTTn solutions use a hybrid configuration to deliver data over more efficient fiber optic lines for the majority of the data transmission while utilizing already existing connections to subscribers from local nodes. Examples of FTTn operators include AT&T's U‐verse and Verizon FiOS."[2]
