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:
