What are the advantages of fiber-to-the-home FTTH?

The advantages of FTTH are mainly 5 points:

First, it is a passive network, from the central office to the user, basically passive in the middle;

Second, its bandwidth is relatively wide, and the long distance is just in line with the large-scale use of operators;

Third, because it is a business carried on optical fibers, there is no problem;

Fourth, because of its wide bandwidth, the supported protocols are more flexible;

Fifth, with the development of technology, including point-to-point, 1.25G and FTTH methods have developed relatively complete functions.

In the optical access family, there are FTTB (Fiber To The Building) fiber to the building, FTTC (Fiber To The Curb) fiber to the curb, FTTSA (Fiber To The Service Area) fiber to the service area and so on.

The optical fiber is directly connected to the user's home, and its bandwidth, wavelength and transmission technology are not limited. It is suitable for introducing various new services. It is the most ideal service transparent network and the ultimate way of access network development.

Although the development speed of mobile communication is amazing, due to the limited bandwidth, the terminal volume cannot be too large, and the display screen is limited, people still pursue fixed terminals with relatively superior performance, that is, to achieve fiber-to-the-home. The charm of fiber-to-the-home lies in its enormous bandwidth, and it is the best solution to solve the "last mile" bottleneck phenomenon from the Internet backbone network to the user's desktop.

Fiber to the home is called FTTH (Fiber To The Home), which refers to directly connecting the fiber to the ONU in the user's home from the operator's OLT room.

The network between the OLT equipment room and the ONU is called ODN (Optical Distribution Network) optical distribution network. The optical distribution network is composed of optical cross-connect boxes, optical joint boxes, optical distribution boxes, optical cables and other equipment. Provide a transmission channel between them.

In ODN, optical cable is the bottom infrastructure of optical signal transmission, which is divided into trunk optical cable, distribution optical cable and home optical cable.
