The defining characteristic of FTTH is that it connects optical fiber directly to residences. It uses optical fiber for most or all of last-mile telecommunications. Optical fiber transmits data using light signals to achieve higher performance. FTTH access networks are basically structured like this: fiber optic cables run from a central office,through a fiber distribution hub (FDH),then through a network access point (NAP),then finally into the home through a terminal that serves as a junction box.

Since the customers have demanded for a more intensive bandwidth,the telecommunication carriers must seek to offer a matured network convergence and enable the revolution of consumer media device interaction. Hence,the emergence of FTTx technology is significant for people all over the world. FTTx,also called as fiber to the x,is a collective term for any broadband network architecture using optical fiber to provide all or part of the local loop used for last mile telecommunications. With different network destinations,FTTx can be categorized into several terminologies,such as FTTH,FTTN,FTTC,FTTB,FTTP,etc. The following parts will introduce the above terms at length.
