FTTH is a foreign language abbreviation for optical fiber directly to the home. Chinese is abbreviated as fiber to the home.
Specifically, FTTH refers to the installation of optical network units (ONUs) at home users or enterprise users, and is the type of optical access network application that is the closest to the user in the optical access series except FTTD (Fiber to the Desktop).
The significant technical features of FTTH are not only providing greater bandwidth, but also enhancing the transparency of the network to data formats, rates, wavelengths, and protocols, relaxing requirements on environmental conditions and power supply, and simplifying maintenance and installation. When it comes to FTTH, you must first talk about fiber access. Optical fiber access refers to the use of optical fiber as the transmission medium between the central office and the user. Optical access can be divided into active optical access and passive optical access. The main technology of optical fiber user network is optical wave transmission technology. At present, the multiplexing technology of optical fiber transmission is developing very fast, and most of them are already in practical use. According to the degree of fiber penetration into the user, it can be divided into FTTC, FTTZ, FTTO, FTTF, FTTH and so on.
