Definition: FTTx


(Fiber To The X) All possible optical fiber topologies from a telecom or cable carrier to its customers, based on the location of the fiber's termination point.

FTTC and FTTN (curb and neighborhood) are similar because the fiber ends outside the building. FTTH and FTTP (home and premises) are synonymous, and FTTE (enclosure) refers to a junction box on a floor or in a department in a large building. For more details, see FTTC, FTTN, FTTP and FTTE.
