4.4.4 Function by unit
1) Remote Drive Unit (RDU)
When receiving TX signals from each band through Remote Optic, RDU filters the signals and
amplifies them with High Power Ampifier. The unit also filters RX signals given through
Multiplexer and amplifies them to send the signals to Remote Optic.
In the unit, there is ATT to adjust gain. RDU devices are varied for each frequency band,
including the following:
