Figure 3.2 – Inside of Remote Unit
Remote Unit receives TX optical signals from Head-‐End and converts them into RF signals. The converted
RF signals are amplified through High Power Amp in a corresponding RDU, combined with Multiplexer
module and then radiated to the antenna port.
When receiving RX signals through the antenna port, this unit filters out-‐of-‐band signals in a
corresponding RDU and sends the results to Remote Optic Module to make electronic-‐optical
conversion of them. After converted, the signals are sent to a upper device of ODU. ROU can be
equipped with up to six RDUs (Remote Drive Unit)
