FTTx technology stands for all fiber technologies in the last mile such as Fiber to the Node( FTTN), Fiber to the Curb( FTTC), Fiber to the Building( FTTB), Fiber to the Desk ( FTTD), Fiber to the Distribution Point ( FTTdp), Fiber to the Office( FTTO), Fiber to the Premises ( FTTP) and Fiber to the Home ( FTTH).
All of these optical connectivity technologies are fiber-to-the-x technologies, where the x is a placeholder for one of the aforementioned technologies. In the various FTTx techniques, the optical fiber is laid from the local exchange, at different distances to the consumer. With Fiber to the Node (FTTN), for example, it extends as far as a distribution cabinet, which may be several kilometers away from the customer site, with Fiber to the Curb (FTTC) as far as the sidewalk, with Fiber to the Premises (FTTP) as far as the customer premises, or with Fiber to the Home (FTTH) as far as the customer's home. Depending on the FTTx concept, the connection is for one customer, a few customers or several hundred customer connections.
