Confidential & Proprietary 46/139 4.4 ROU (Remote Optic Unit) ROU receives TX optical signals from ODU or OEU 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 or OEU. ROU can be equipped with up to three RDUs (Remote Drive Unit) and the module is composed of maximal Dual Band. Figure 4.25 – ROU Outer Look ROU is designed in a cabinet, and provides the following functions and features. 4.4.1 Specifications of ROU Item Spec.
