eROU receives TX optical signals from eHUB and converts them into RF signals. The converted RF signal is
radiated to the antenna port via the AMP and Multiplexer. When receiving RX signals through the antenna
port, this unit filters out-of-band signals in a corresponding Multiplexer and sends the results to OPTIC to
make electronic-optical conversion of them. After converted, the signals are sent to a upper device of
eHUB.
For this application, eROUa receives RF signals from eROU. The received RF signals are radiated through
the AMP and multiplexer to the antenna ports. When the device receives an RX signal through the antenna
port, it filters out-of-band signals from the appropriate multiplexer and transmits the results to the RF
signal. The signal is transmitted to the upper unit of the eHUB.
