What's the difference between FTTB and FTTH

1, the equipment is different: FTTB installation requires the installation of ONU equipment; FTTH ONU equipment installed in a box somewhere in the building, the user installed through the five types of wire access to the user indoor.

2, different installation: FTTB is fiber optic cable into the home, the user can use a fiber optic telephone, broadband, IPTV and other services; FTTH is fiber optic cable to the building or to the building.

3, the network speed is different: FTTH than FTTB said that there is a higher speed of Internet access.

FTTH is a foreign language abbreviation for fiber optic direct to the home, the Chinese abbreviation for fiber to the home. Specifically, FTTH refers to the optical network unit (ONU) installed at the residential user or business user, is the optical access series in addition to FTTD (fiber to the desktop) outside the closest user type of optical access network applications.

The distinctive technical features of FTTH are not only the provision of greater bandwidth, but also the enhanced transparency of the network to data formats, rates, wavelengths and protocols, the relaxation of requirements such as environmental conditions and power supply, and the simplification of maintenance and installation. When it comes to FTTH, we must first talk about fiber optic access. Fiber optic access refers to the use of fiber optics as the transmission medium exclusively between the local end and the user.

Fiber optic access can be divided into active optical access and passive optical access. The main technology of fiber optic subscriber network is optical wave transmission technology. At present, the multiplexing technology of fiber optic transmission is developing quite fast, and most of them are already in practical use. According to the degree of fiber optic penetration into the user, it can be divided into FTTC, FTTZ, FTTO, FTTF, FTTH, etc.
