Latest company news about The way of fiber optic broadband access, the difference between FTTH and FTTB

1. FTTH is the foreign language abbreviation of fiber optic direct to the home, which means fiber to the home in Chinese.

Refers to the direct installation of the optical network unit (ONU) at the home user or business user (where the user needs it).

1. Notable technical features of FTTH: not only provide greater bandwidth, but also enhance the transparency of the network to data format, rate, wavelength and protocol, relax the requirements for environmental conditions and power supply, and achieve faster Internet access and better network quality Stable, online high-definition video, Internet TV, high-speed download, large-scale online games and other network applications are more powerful.

2. Users can use telephone, broadband, IPTV and other services through one optical fiber, but when installing broadband, they need to install ONU equipment provided by the operator (that is, optical modem, a kind of photoelectric conversion equipment), which simplifies maintenance and installation.

3. The home broadband installed now is all connected in this way. On the basis of maintaining the user's existing communication services, the optical fiber line is directly connected to the user's home, replacing the original cable line, and the communication capability and quality are greatly improved. After the optical fiber is directly connected to the home, the optical modem is used to convert the "photoelectric" signal, and the exclusive broadband has the advantages of large capacity, wide frequency bandwidth, and more stability. The access band basically starts at 100M, which is our main broadband access at present. Way.
