2 Introduction to the RRU3220

About This Chapter

The RRU3220 is a type of remote radio unit supporting the FDD mode.

The RRU3220 implements the following functions:

l Receives downlink baseband data from the BBU and transmits uplink baseband data to theBBU for the communication between the RRU and the BBU.

l Receives RF signals from the antenna system, down-converts the RX signals toIntermediate Frequency (IF) signals, performs amplification, and analog-to-digital (A/D)conversion. The TX channel performs shape filtering of the downlink signals, digital-to-analog(D/A) conversion, and up-conversion of RF signals to transmit band.

l Multiplexes RX and TX signals, which enables these signals to share the same antennapath. It also filters RX and TX signals.

2.1 Exterior of the RRUThe RRU has a modular structure. The external ports of the RRU are located at the bottom ofthe RRU and in the cabling cavity.

2.2 Panels of the RRUThe RRU module has a bottom panel, cabling cavity panel, and LED panel.

2.3 LEDs on the RRUThe six LEDs on the RRU are on the LED panel, indicating the running status of the RRU.

3 RRU CablesRRU3220



Issue 04 (2010-10-25)

Exterior

The CPRI optical cable is categorized into the multi-mode optical cable and single-mode opticalcable. When the distance between the BBU and the RRU is shorter than 100 m, a multi-modeoptical cable is required. When the distance between the BBU and the RRU is longer than 100m, a single-mode optical cable is required. A single-mode optical cable connects the BBU to theODF and the ODF to the RRU to transmit CPRI signals.

A multi-mode optical cable is a multi-mode cable with a DLC connector at each end. Figure3-4 shows the multi-mode optical cable.

Figure 3-4 Multi-mode optical cable

(1) DLC connector (2) Branch cable (3) Label on the branch cable

When a multi-mode optical cable is used for connection between the BBU and RRU, the branchcables on the BBU side and RRU side are 0.34 m and 0.03 m long respectively. When a multi-mode optical cable is used for connection between RRUs, the branch cables on both RRU sidesare 0.03 m long.

A single-mode optical cable has a DLC connector at one end and two FC connectors at the otherend, as shown in Figure 3-5.

Figure 3-5 Single-mode optical cable

(1) DLC connector (2) Branch cable

(3) Label on the branch cable (4) FC connector

When a single-mode optical cable is used for connection between the BBU and the ODF, thebranch cables on the BBU side and ODF side are 0.34 m and 0.8 m long respectively.

When a single-mode optical cable is used for connection between the ODF and RRU, the branchcables on the BBU side and ODF side are 0.03 m and 0.8 m long respectively.

NOTEThe CPRI optical cable must be connected to the optical module in the CPRI port on the BBU or RRU. Themulti-mode optical cable and single-mode optical cable are used for the multi-mode optical module and single-mode optical module respectively.

4 Auxiliary Devices of the RRU

About This Chapter

The auxiliary devices of the RRU consist of the Indoor Floor installation support (IFS06),Outdoor Cable Conversion Box (OCB), and Smart Bias Tee (SBT).

4.1 IFS06The Indoor Floor installation Support (IFS06) is used for installing RRUs indoors.

4.2 OCBThe Outdoor Cable Conversion Box (OCB) interconnects cables of different core diameters.The power cables shipped with the RRU cannot support long-distance power transfer. Therefore,when the power supply is far from the equipment, the OCB can be used to connect the powercable of the RRU and a cable with a large core diameter, which can transfer power for a longdistance.

4.3 SBTThe Smart Bias Tee (SBT) is used when the eNodeB is configured with the Smart TowerMounted Amplifier (STMA) and Remote Electric Tilt (RET) antenna. The SBT converts theRET control signals from the eNodeB into the On-Off Keying (OOK) signals, couples the OOKsignals and 12 V DC signals into the feeder, and then transmits the signals to the antenna.

when the power supply is far from the equipment, the OCB can be used to connect the powercable of the RRU and a cable with a large core diameter, which can transfer power for a longdistance.

Application ScenarioThe application scenario of the OCB is shown in Figure 4-3.

4.3 SBTThe Smart Bias Tee (SBT) is used when the eNodeB is configured with the Smart TowerMounted Amplifier (STMA) and Remote Electric Tilt (RET) antenna. The SBT converts theRET control signals from the eNodeB into the On-Off Keying (OOK) signals, couples the OOKsignals and 12 V DC signals into the feeder, and then transmits the signals to the antenna.

Applications

l In the SBT, the control signals from the RRU are converted from the RS485 signal levelinto the OOK signal level, and then the 12 V DC signals, OOK signals, and RF signals arecombined. The combined signals are transmitted to the Antenna Line Device (ALD) suchas the STMA and Remote Control Unit (RCU) through the feeder.



4-5

l The OOK signals from the feeder are converted into the RS485 signals and then transmittedto the RRU.

Figure 4-5 shows the application scenario of the SBT.

NOTEFor details about the RF feeder between the RRU and the SBT, see 3.5 RF Jumper for the RRU. The DINmale connector at one end of the RF jumper is connected to the ANT_TX/RXA port on the RRU, and the DINfemale connector at the other end is linked to the SBT connector.
