BMU

The BMU has the donor and service cable ports opposite the ports of other repeaters. A

cabinet for a BMU has no CU PCBA and no amplifier PCBAs but instead contains a FOU with

a FON and a DPX. By adding WDMs and splitters to the FOU, up to four FORs can be fed in

parallel by a BMU with double or single fiber communication. A high cover can be equipped as

well providing connections for up to eight FORs. PCBA positions are illustrated in the Figure 1-

8 and a block diagram is located in Appendix A. The most common unit used to get the BMU

functionality is the 19" indoor rack mounted OCM illustrated in Figure 1-9. The OCM is

described in the Fiber Optic Equipment Operation and Maintenance Manual.
