Fibre To The Home - FTTH is a method of transmission for fiber optic communication. It is the direct connection of optical fiber to the user's home (where the user needs it).
This fiber optic communication method and strategy is different from FTTN, FTTC, HFC (Hybrid Fiber Coaxial), etc. They all need to rely on traditional metal wires, including twisted pair and coaxial cable, for the "last mile" of information transmission.
The advantages of fiber to the home approach
1. It is a passive network, from the bureau to the user, the middle can basically be passive;
2. Its bandwidth is relatively wide, long distance just in line with the operator's large-scale use of the way;
3. because it is a service carried on fiber, there is no problem;
4. Because of its wide bandwidth, the supported protocols are more flexible;
5. With the development of technology, including point-to-point, 1.25G and FTTH way are developed more complete functions.
In the optical access family, there is also 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 user's home, its bandwidth, wavelength and transmission technology types are not limited, suitable for the introduction of a variety of new services, is the most ideal service transparent network, is the ultimate way to develop the access network.
Although the development of mobile communication is amazing, but because of its limited bandwidth, the terminal size is not too large, display screen is limited and other factors, people still pursue the relatively superior performance of fixed terminals, which is the hope to achieve the fiber to the home. The appeal of fiber to the home is that it has great bandwidth, and it is the best solution to solve the "last mile" bottleneck phenomenon from the Internet backbone to the user's desktop.
As the technology is updated, the cost of FTTH is greatly reduced and will soon be comparable to DSL and HFC networks, which makes FTTH practical. In addition, FTTH technology is also used to solve the "last mile" problem in the information superhighway. FTTH+Ethernet is much faster than ADSL and ISDN.
Disadvantages
Based on the MAC speed limit mode, the latency will increase when the broadband runs full.
Rate FTTH provides a maximum of 4M upstream and 100M downstream, which are not peer-to-peer lines, FTTB is peer-to-peer, providing a maximum of 10M.
