Figure 2-9 shows an BMU with separate RX/TX fiber optic cables to one
FOR. By using WDMs and OSPs, up to four FORs can be fed in parallel
by a BMU with double or single fiber communication. Up to eight FORs
can be fed with a high cover and two FOUs.
1. Connect the BTS antenna output RF cable to the ANT port of the
DC unit to the left in the cabinet. Use an N type male connector.
2. Connect an RF cable from the DPX port of the DC unit to the left in
the repeater to the BTS antenna. Use an N type male connector.
3. Connect the RX and TX fiber optic cables from the FON board
located in the upper part of the FOU to an FOR.
4. Connect station ground, if to be used (see page 2-7).
5. Mount the mains plug to the mains cord (if to be used) but do not
connect the mains (see page 2-7).
