2.4.2 The ODU Power Feeder
The ODU Power Feeder is used to provide power (-48 VDC) to the ODUs. It
transfers all signals transparently between the AU and the ODU, while injecting
DC power received from an external source. Each ODU Power Feeder unit can
serve up to four ODUs. Up to three ODU Power Feeder units can be installed in a
1U Feeder panel.
