the difference between p>FTT and FTTH:
FTTB, that is, Fiber to The Building, uses digital broadband technology to directly send optical fiber to the community, and then to all users through twisted pairs (super five twisted pairs or four unshielded twisted pairs).
FTTH is the foreign language abbreviation of FTTH, and the Chinese abbreviation is FTTH. Specifically, FTTH refers to the installation of optical network unit (ONU) at home users or enterprise users, which is the application type of optical access network closest to users except FTTD.
the obvious technical features of p>FTTH are not only providing larger bandwidth, but also enhancing the transparency of the network on data format, rate, wavelength and protocol, relaxing the requirements on environmental conditions and power supply, and simplifying maintenance and installation.
