Fiber-to-the-x (FTTx) optical access

(FTTx, x = H for home, P for premises, C for curb and N for node or neighborhood, O for office, SA for service area, B for Building) where FTTH FTTH, FTTP FTTP, FTTC fiber to roadside / cell, FTTN fiber to the node, FTTO fiber to the office, FTTSA fiber to the service area.

Fiber to the home (FTTH) in 20 years people continue to pursue dreams and technical direction to explore, but because of cost barriers, technology, demand and other aspects, has not been large-scale promotion and development. Because of this, many in the FTTx (fiber to the home in particular, fiber to the premises) Regarded as the optical communications market recovery important turning point. And it is expected in the next few years, FTTH network will have greater development.

The optical fiber according to the user's distance to the classification shown in Figure 1, the optical fiber can be divided into the exchange boxes (Fiber To The Cabinet; FTTCab), fiber to the curb (Fiber To The Curb; FTTC), fiber to the building (Fiber To The Building; FTTB) and FTTH (fiber To The home; FTTH) 4 kinds of service form. US operator Verizon will FTTB and FTTH fiber to the premises collectively (Fiber To The Premise; FTTP). These services can be referred to FTTx.
