Any person involved in installation or service of the DAS should understand and follow these safety guidelines.
- Obey all general and regional installation and safety regulations relating to work on high voltage installations, as well as regulations covering the correct use of tools and personal protective equipment.
- The power supply unit in repeaters contains dangerous voltage levels, which can cause electric shock. Switch the mains off prior to any work in such a repeater. Any local regulations are to be followed when servicing repeaters.
- When working with units outdoors, make sure to securely fasten the door or cover in an open position to prevent the door from slamming shut in windy conditions.
- Use this unit only for the purpose specified by the manufacturer. Do not carry out any modifications or fit any spare parts which are not sold or recommended by the manufacturer. This could cause fires, electric shock, or other injuries.
- Any DAS system or Fiber BDA will generate radio (RF) signals and continuously emit RF energy. Avoid prolonged exposure to the antennas. SOLiD recommends maintaining a 500 cm minimum clearance from the antenna while the system is operating.
- Do not operate this unit on or close to flammable materials, as the unit may reach high temperatures due to power dissipation.
- Do not use any solvents, chemicals, or cleaning solutions containing alcohol, ammonia, or abrasives on the DAS equipment. Alcohol may be used to clean fiber optic cabling ends and connectors.
- To prevent electrical shock, switch the main power supply off prior to working with the DAS System or Fiber BDA. Never install or use electrical equipment in a wet location or during a lightning storm.
- Do not look into the ends of any optical fiber or directly into the optical transceiver of any digital unit. Use an optical spectrum analyzer to verify active fibers. Place a protective cap over any radiating transceiver or optical fiber connector to avoid the potential of radiation exposure. Confidential & Proprietary 5/28
- Allow sufficient fiber length to permit routing without severe bends.
- For pluggable equipment, make sure to install the socket outlet near the equipment so that it is easily accessible.
- A readily accessible disconnect device shall be incorporated external to the equipment.
- The power of this system shall be supplied through wiring installed in a normal building. If powered directly from the mains distribution system, it shall be used with additional protection, such as an overvoltage protection device
- Only 50 ohm rated antennas, cables, and passive equipment shall be used with this remote. Any equipment attached to this device not meeting this standard may cause degradation and unwanted signals in the bi-directional system. All components connected to this device must operate in the frequency range of this device.
- Only 50 ohm rated antennas, cables, and passive components operating from 150 - 3 GHz shall be used with this device.
- The head end unit must always be connected to the Base Station using a direct cabled connection. This system has not been approved for use with a wireless connection via server antenna to the base station.
- Access can only be gained by SERVICE PERSONS or by USERS who have been instructed about the reasons for the restrictions applied to the location and about any precautions that shall be taken; access is through the use of a TOOL or lock and key, or other means of security, and is controlled by the authority responsible for the location.

Confidential & Proprietary 7/28 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. When receiving RX signals through the antenna port, this unit filters out-of-band signals in a corresponding HRDU and sends the results to R-OPTIC to make an electronic-to-optical conversion. After conversion, the signals are sent to the upper device of ODU. HROU_4000 can be equipped with up to four HRDUs (High Remote Drive Unit) and each module supports a single band only. HROU_4000 has a digital board to improve the PAUs linearity by performing DPD (Digital Pre-Distortion). Also, CFR works to improve the PAPF performance. Since C-Band and Auction 110 band uses TDD technology, the digital board of HROU is also equipped with the SDM to acquire the synchronization for 5G NR TDD signals. Figure 1.

They are the DC/DC PSU receiving input -48V and the AC/DC PSU receiving input 110V/220V from external. RPSU has a circuit brake to turn the power ON/OFF and has an LED indicator at the top to check if the input power is normally supplied. Figure 5. AC-DC RPSU Outer Look Figure 6.

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. R OPTIC Outer Look 2.1.3.4 HROU_4000_DTU Remote Central Processor Unit (RCPU) HROU_4000_DTU can monitor and control each module of HROU_4000. This unit receives and analyzes upper communication data from Remote Optic and reports the unit's value to upper devices. On the front of the module, it has LED indicators to show system status, letting you check any abnormalities at a time. On the same front, it also has communication LED Indicators to show communication status with upper devices. Through the local port, the unit enables you to check and control device status through a PC or laptop. Digital transmission Unit (DTU) HROU_4000_DTU performs DPD to improve the HRDU PAU efficiency. Also, CFR is used in DTU as a technique to reduce the PAPR of the transmitted signal. HROU_4000_DTU also acquires the synchronization for 5G NR TDD signals. Confidential & Proprietary 15/28 Figure 8.
