FTTx technology is mainly used for accessing fiber-optic network, ranging from central office equipment of regional telecommunications room to the user terminal equipment. Central office equipment refers to the optical line terminal(OLT) and customer premise equipment(CPE) refers to the optical network units(ONU) or optical network terminals(ONT). According to the distance of the fiber to the user, FTTx can be divided into four kinds of service forms. There are Fiber To The Cabinet(FTTCab),Fiber To The Curb(FTTC), Fiber To The Building(FTTB) and Fiber To The Home(FTTH).
1.FTTC
FTTC is the most important service form for Fibercasa currently, servicing for residential users primarily. Fibercasa suggests that ONU equipment will be placed at the roadside cabinet , and we can employ the out of the coaxial cable of ONU transmitting CATV signals or twisted-pair transmitting telephone and Internet services.

2.FTTB
According to Service object , there are two forms about FTTB: one is the apartment building customer service, and the other one is the commercial building company services. ONU are both set in the basement of the building wiring box office, but the ONU of the apartment building is an extension of FTTC and the commercial building is for medium and large enterprises so it must increase the rate of transmission in order to provide high-speed data, e-commerce, video conferencing broadband services.

3.FTTH
About FTTH, ITU considered that it is FTTH that the distance between photoelectric converter of fiber tip (otherwise known as media converter MC) to the user's desktop does not exceed 100 meters. FTTH extends the distance of optical fiber to the end-user home, so the family can provide a variety of broadband services, such as VOD,shopping at home, schooling at home etc., and provide more business opportunities. With WLAN technology, It makes the combination of broadband and mobile，it can achieve the vision of broadband digital home in the future.

4.FTTP
FTTP (fiber to the premise, fiber to the user location)is the North American term. FTTP has been extended the cable to the home or business. Since the optical fiber can provide more bandwidth than twisted-pair or coaxial cable used in last mile, operators use it to provide voice, video and data services. FTTP has 25M to 50Mbps or higher speed. While the maximum speed of other types of broadband services is approximately 5M to 6Mbps. In addition FTTP also supports full symmetric services.
