The RRU has the following functions:

l Receiving the downlink baseband data from the BBU, transmitting the uplink baseband

data to the BBU, and communicating with the BBU.

l Receiving RF signals from the antenna, performing down-conversion, amplification, and

analog-to-digital conversion, apart from filtering downlink signals and performing digital-

to-analog conversion and up-conversion to the transmit band.

l Multiplexing the RX and TX signals in the same RF channel and filtering the signals.

NOTE

l When the distance between the RRU and the antenna is within 14 m, one end of the RF jumper is connected

to the ANT-TX/RXA or ANT-TX/RXB port at the bottom of the RRU, and the other end is connected to

the antenna.

l When the distance between the RRU and the antenna exceeds 14 m, the RF jump connects to the feeders before the feeders connect to the RRU and antenna. If the RF jumper is provided by the customer, the length

of the RF jumper should not exceed 2 m and be as short as possible.

Appearance

The RF jumper has one DIN male connector at each end, as shown in Figure 3-5.

Figure 3-5 RF jumper

The alarm cable of RRU is a shielded straight through cable. It transmits 2-channel Boolean

alarm signals and 1-channel RS485 signal from external equipment to the RRU. Thus, the

external signals are monitored.

Appearance

The cable has a DB9 waterproof connector at one end and eight cord end terminals at the other

end, as shown in Figure 3-6.

NOTE

If the cord end terminals of the cable do no match the ports on the external devices, cut off the cord end

terminals and make proper terminals on site.

3.7 AISG Multi-Wire Cable for the RRU

The 5-m-long AISG multi-wire cable is used to connect the RRU with the RCU and to transmit

the base station signals for controlling the RET antenna. The AISG cable is optional.

NOTE

The Remote Control Unit (RCU) is the driving motor of the phase shifter inside the RET antenna. The RCU

receives and executes the control commands from the BTS to drive the stepper motor. The adjustable phase

shifter inside the antenna is driven by the actuator so that the tilt of the antenna can be changed.

Appearance

The AISG multi-wire cable has a DB9 waterproof male connector at one end, and a standard

AISG female connector at the other end, as shown in Figure 3-7.

About This Chapter

The RRU auxiliary device is the Outdoor Cable Conversion Box (OCB).

4.1 OCB

The 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, a cable that has a large core diameter is required

to obtain power, and the OCB needs to be used to connect the power cable of the RRU and the

cable of a large core diameter.
