Fiber to the home (FTTH), also called "fiber to the premises" (FTTP), is the installation and use of optical fiber from a central point directly to individual buildings such as residences, apartment buildings and businesses to provide unprecedented high-speed Internet access. FTTH dramatically increases the connection speeds available to computer users compared with technologies now used in most places.
There are five main advantages of FTTH:
First, it is a passive network from the central office to the user, the intermediate can be connected by passive products.
Second, its bandwidth is relatively wide, and the long distance fits the operators’ large-scale use.
Third, it is carried on optical fiber, anti-interference.
Fourth, because of its relatively wide bandwidth, the supported protocols are more flexible;
Fifth, with the development of technology, including point to point, 1.25G and FTTH way have developed a relatively complete function.
In the family of optical access, there are FTTB (Fibre To The Building) fiber to the building, FTTC (Fibre To The Curb) Fiber to the Curb, FTTSA (Fibre To The Service Area) fiber to the service area and so on.
The optical fiber directly to the home user, bandwidth, and wavelength transmission technology types are not limited, and suitable for introduction of new services, is the ideal transparent network service, the access network is the ultimate way of development.
Although the mobile communications developed at an alarming rate, the limited bandwidth, the terminal can not be too much big, limited by factors such as the display screen, it is still relatively dominant performance to pursue a fixed terminal and hope to reach fiber to the home.
Fiber to the home's charm lies in its great bandwidth, it is the solution from the Internet backbone to the user's desktop, "last kilometer" best of bottlenecks.
With the upgrading of technology, it greatly reduces the cost of fiber to the home, and soon can be reduced considerably with DSL and HFC networks, which makes practical FTTH possible. According to reports, as early as 1997, Japan's NTT started the development of FTTH, after 2000 the users increase quickly as the cost reduced; the United States’ FTTH increased by more than 200% in the number after the year 2002.
