Figure 3.5 – Internal View of Remote Unit The N2ROU 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. RX signals received from the antenna port are filtered through the multiplexer module, amplified at the RDU modules, and converted into optical signals via optical module.
