An article to help you figure out what is FTTX?

Fiber-to-the-x (FTTx) fiber optic 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 Fiber-to-the-Home, FTTP Fiber-to-the-Premises, FTTC Fiber to the curb/neighborhood, FTTN Fiber to the node, FTTO Fiber to the office, FTTSA Fiber to the service area.

Fiber to the home (FTTH) is 20 years people continue to pursue the dream and explore the direction of technology, but due to cost, technology, demand and other obstacles, so far has not been a large-scale promotion and development. Because of this, many knowledgeable people regard FTTx (especially fiber-to-the-home and fiber-to-the premises) as an important turning point for the recovery of the optical communications market. And it is expected that FTTH network will have greater development in the next few years.

Based on the distance from the fiber to the subscriber, it can be classified into four types of services, including Fiber To The Cabinet (FTTCab), Fiber To The Curb (FTTC), Fiber To The Building (FTTB) and Fiber To The Home (FTTH). Fiber To The Home (FTTH) and Fiber To The Building (FTTB). The U.S. operator Verizon refers to FTTB and FTTH together as Fiber To The Premise (FTTP). The above services can be collectively referred to as FTTx.

1.FTTC

FTTC is currently the most important form of service, mainly for residential users as a service, the ONU equipment placed in the roadside chassis, the use of coaxial cable out of the ONU to transmit CATV signals or twisted-pair transmission of telephone and Internet access services. ftttc transmission rate of 155Mb/s. ftttc and the switching exchange interface with the ITU-T developed interface standard V5.

2. FTTB

There are two kinds of FTTB according to the service object distinction, one is the user service of the apartment building, and the other is the company line number service of the commercial building, and both of them set the ONU in the basement distribution box of the building, only that the ONU of the apartment building is the extension of the FTTC, while the commercial building is for the medium and large-scale enterprise units, which must improve the transmission rate to provide high-speed data, e-commerce, video conferencing, and so on. broadband services.

3. FTTH

As for FTTH, ITU considers that the situation where the optical converter (or media converter MC) from the end of the fiber to the user’s desktop is no more than 100 m. FTTH extends the distance of the optical fiber to the end-user’s home, making it possible to provide a variety of different broadband services within the home, such as VOD, shopping at home, taking classes at home, and so on, which provides more business opportunities. If combined with WLAN technology, it will make broadband and mobile combination, then it can achieve the vision of the future broadband digital home.

4.FTTP

FTTP (fiber to the premise, fiber to the user’s location), North American terminology, FTTP will be fiber optic cable has been extended to the home or business. Because fiber can provide more bandwidth than the twisted pair or coaxial cable used in the last mile, carriers use it to provide voice, video, and data services.FTTP has speeds of 25M to 50Mbps or higher, compared to other types of broadband services that have maximum speeds of about 5M to 6Mbps.In addition, FTTP also supports fully symmetrical services.

5. FTTZ

FTTZ (Fiber To The Zone), refers to the fiber to the cell. FTTx technology is mainly used for access network fiber optic, the scope from the regional telecommunications room of the local equipment to the user terminal equipment, the local equipment for the Optical Line Terminal (Optical Line Terminal; OLT), the user equipment for the Optical Network Unit (Optical Network Unit; ONU) or Optical Network Unit (ONU). The local equipment is Optical Line Terminal (OLT) and the user equipment is Optical Network Unit (ONU) or Optical Network Terminal (ONT).
