Connecting FOR
Figure 2-11 shows a FOR for service antenna and separate RX/TX fiber
optic cables from a BMU. By adding WDMs and OSPs, a number of FORs
can be fed by one BMU with double or single fiber communication.
1. Connect the service antenna coaxial cable to the left in the cabinet
(’MS’ in Figure 2-10). Use an N type male connector.
2. Connect the RX and TX fiber optic cables from the BMU to the FON
board located in the upper part of the FOU.
3. Connect station ground, if to be used (see page 2-7).
4. Mount the mains plug to the mains cord (if to be used) but do not
connect the mains (see page 2-7).
5. Connect external alarm and optional door open alarm, if this feature
is to be used. Descriptions are found on page 2-13.
6. Connect the R2R cables, if this feature is to be used (see page 2-14).
7. Connect a mains breakdown relay, if mains breakdown alarm is to be
used (see page 2-15).
