FTTH refers to the optical network unit is installed in the enterprise user or home users, in the optical access Series in addition to fiber to the desk and closest to the user of the optical access network application types. FTTH has significant advantages, in addition to enhance network data format, wavelength and rate transparency, on the environment and the requirements of power supply is not too high; and can provide greater bandwidth. FTTH and fiber access has very close links. Optical fiber access refers to the user and terminal optical fiber as the transmission medium between completely. Because the optical fiber transmission multiplexing technology fast development, most of the current has been achieved practical. F FTTH ( fiber to the home ) is an optical network unit ( ONU ) installed in a home user or business user, is closest to the user of the optical access network application types. As the video, digital TV, IPTV high-bandwidth multimedia applications, business customers on the network bandwidth, stability demand rise, domestic about the discussion of the FTTH gradually warmi
