FTTH fiber to the home common sense

Speaking of FTTH, we must first talk about optical access. Fiber optic access refers to the complete use of optical fibers as transmission media between the Bureau and users. Optical fiber access can be divided into active optical access and passive optical access. The main technology of optical fiber subscriber network is optical wave transmission technology. At present, the multiplexing technology of optical fiber transmission has developed rapidly, and most of them have been put into practice. According to the degree of fiber penetration, it can be divided into FTTC, FTTZ, FTTO, FTTF, FTTH and so on.
