2.1 PS2ROU (Public Safety 2W Remote Unit)
PS2ROU receives TX optical signals from ODU and converts them into RF signals. The converted RF signals
are amplified through Power Amp in a corresponding PS2RDU band combined with UDCU, PAU and Cavity
Filter, 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 PS2RDU and sends the results to R-OPTIC to make electronic-optical conversion of them.
After converted, the signals are sent to a upper device of ODU. PS2ROU can be equipped with up to three
PS2RDUs and the module supports single band only.
