Section3 System configuration and Functions 3.1 HROU (High power Remote Optic Unit) 3.1 HROU (High power Remote Optic Unit) HROU consists of two unit, one is HMRU(High power Main Remote Unit) and the other is HARU(High power Add‐on Remote Unit). The biggest difference between HMRU and HARU is whether R‐OPTIC module exist or not in the enclosure. HMRU receives TX optical signals from ODU and converts them into RF signals.

3.1.3.2 Remote Power Supply Unit ( RPSU) There are 2types of RPSU in the HROU for supply to active module in the enclosure and receive power from external. They are the DC/DC PSU receiving input ‐48V and the AC/DC PSU receiving input 110V/220V from external. As order, either of the two types should be decided. MS Connector, which uses ports to receive inputs, is designed to accept any of AC and DC.

It also has internal ATT for optical compensation to compensate for optical cable loss.
Figure 9. R OPTIC Outer Look 3.1.3.4 Remote Central Processor Unit (RCPU) RCPU can monitor and control each module of HROU. This unit receives and analyzes upper communication data from Remote Optic and reports the unit's own value to upper devices. At the front of the module, it has LED indicator to show system status, letting you check any abnormalities at a time. At the same front, it also has communication LED Indicators to show communication status with upper devices.
3.1.4 Bottom of HROU 3.1.4.1 Functions The Bottom look of HROU depends on the CU(combine unit) option . Basically, The CU has two antenna ports. But , If not need to install CU in the enclosure, The number of antenna ports on the bottom of HROU will be change 4 ports with DIN‐ type . Figure 11.

The way to install the ALM IN/OUT Connector comply with below procedures Figure 23. How to install ALM IN/OUT Cabling The procedures are Peel off sheath of the cable. Assemble all components on cable as following. Connect all wires to insert according to wire list, then tighten all small screws. The torque for small screws is 0.2Nm. Assemble plastic nut to main body. Recommended torque : 1.0Nm. (Note : The key inside the main body must go straight to slot of insert.
4.1.9 Mounting of HRDU HROU has slots to enable up to four HRDU modules to be mounted in it. You can mount a HRDU into designated slot surely. It is not possible to provide services with a HRDU module alone; you need to connect HRDU cavity duplexer antenna port with CU’s designated port. Figure 24. How to mount HRDU The Remote Unit holds a maximum of 4 HRDUs. Guide brackets on the bottom of each HRDU slot simplify installation as described below. MRDU installation requires a +No.1 tip size screwdriver.
Figure 25.
The procedures are 1. Lift the HRDU onto the guide bracket and ensure the MRDU is level left to right 2. Push the HRDU into the corresponding slot in the direction of the heat sink while levelling the MRDU to guide bracket 3. Make sure the HRDU is firmly inserted into the corresponding slot. Tighten the 4 corner screws to secure the unit 4. Install HRDU blank cards in all unused slots in the remote.
