2.1.2 FTTB

Fiber to The Building (FTTB) is a broadband access mode based on the

improved, hi-speed and optical-fiber LAN. In this access mode, the optical

fiber is extended to the building and then the network cable is deployed to each

home, so this access mode is most reasonable, most practical and most

effective.

In FTTB, after OLT is put at the center of the machine room and ONU is

installed beside the corridor switch, a networking layout for the whole building

should be conducted according to actual requirements. OLT and ONU in

FTTH are also connected in point-to-multipoint mode through the optical

splitter. For the detailed topology, see figure 2-2:
