Fiber To The Home, fiber to the home, is a transmission method of fiber optic communication. The notable technical feature of FTTH is that it not only provides greater bandwidth, but also enhances the transparency of the network to data formats, rates, wavelengths and protocols, relaxes the requirements for environmental conditions and power supply, and simplifies maintenance and installation. PON technology has become the focus of global broadband operators, and is considered to be one of the best technical solutions to realize FTTH.

FTTH, fiber-to-the-home, is the best model for full-service, high-bandwidth access requirements so far.

There are two main paths for the development of FTTH - active optical network and passive optical network.

Active optical network has the characteristics of long transmission distance, but the degree of special equipment is large, the port price is relatively high, the equipment installation is very limited, it is easy to receive electromagnetic interference from the surrounding environment, and the failure points of the chain network are increased, and the maintenance cost is relatively high. high.

Because the passive optical network is a pure medium network, it has the ability to resist the influence of electromagnetic interference naturally, which reduces the failure points of the access network, and has high system reliability and low maintenance cost. At the same time, the FTTH of the passive optical network mode has good transparency and can support the application of various standards, which is more suitable for large-scale development of users. Passive optical network has gradually become the mainstream development direction of FTTH.

The physical layer of FTTH adopts optical fiber, and the use of optical network provides a good basic guarantee for the high-bandwidth service transmission capability. However, only the physical layer is not enough. To realize the transmission of information, it is more important to control the second layer. Therefore, the development of FTTH has experienced a revolution on the second layer of the network - the process of developing from ATM to Ethernet, corresponding to the two series of APON and E/GPON respectively.
