For many home users, FTTH connects fiber optic and optical network units (ONU) directly to the home, which is a form of fiber-optic access that is close to the user in addition to FTTD (fibre to desktop, Fiber To The Desk).

With the generalization of fiber broadband access form, it needs to be explained that the current FTTH broadband access is not simply referring to fiber-to-home, has been referred to FTTO, FTTD, FTTN and other fiber-to-home access forms. FTTx-LAN is a broadband access scheme that uses fiber-optic plus 5 twisted pair lines to achieve “100Mbps to cells or buildings, 1-10Mbps to homes” – switches and bureau-side switches in the community are connected to the optical network unit (ONU), and the five-type twisted-pair integrated cabling is used in the cell.

Users can access the Internet at speeds of 1-10Mbps. Unlike FTTH, a single-family bandwidth scheme, FTTx-LAN bandwidth is shared by multiple users or households, and when there are more shared users, its broadband bandwidth or network speed is difficult to guarantee.
