Section2 System Configuration and Functions System Configuration and Functions 2.1 High power 5G Remote HROU_4000 is a remote unit supporting both SISO and MINO service of C-Band. HROU_4000 receives TX optical signals from ODU and converts them into RF signals. The converted RF signals are amplified through high-power amps in the corresponding HRDU bands combined with UDCU, PAU, and Cavity duplexer, and then radiated to the antenna port. -

Page 13: Function By Unit
2.1.3 Function by unit 2.1.3.1 High Remote Drive Unit (HRDU) When receiving TX signals from each band through Remote Optic, HRDU filters the signals and amplifies them with High Power Amplifier. The unit also filters RX signals given through a cavity filter and amplifies them to send the signals to Remote Optic. -
Page 14: Remote Power Supply Unit (Rpsu)
2.1.3.2 Remote Power Supply Unit (RPSU) There are 2 types of RPSU in the HROU to supply active modules in the enclosure and receive power from the external. They are the DC/DC PSU receiving input -48V and the AC/DC PSU receiving input 110V/220V from external. -
Page 15: Remote Optic (Hroptic_4000)
2.1.3.3 Remote Optic (HROPTIC_4000) Remote Optic converts optical signals into RF signals and performs vice versa. It also has internal ATT for optical compensation to compensate for optical cable loss. It provides two paths in pairs (TX/RX) to transport RF signal to ADD On port. Figure 7. -
Page 16: Multiplexer
Figure 8. HROU_4000_DTU Outer Look 2.1.3.5 Multiplexer A multiplexer is called a Combine Unit (CU) since it works as a module to combine or distribute multiple signals into one or two antennas. This device has a port to combine multiple signals. You need to connect the input and output ports of RDU to the corresponding port of the multiplexer. -
