Connections
End A is connected to the PWR interface of ZXSDR R8882.
End B is connected to the corresponding terminals on the power supply adapter.
Note:
The EPBC embedded lightning arrester is used for the device and therefore external
signals are not transmitted through the cable transit box. During installation, the field
engineer needs to make a cable on site in accordance with the available power aviation
head and connect the power cable with the power connector.
4.4 Antenna Feeder Cable
Function
The antenna feeder cable connects the antenna feeder interface on the ZXSDR R8882
chassis to the main feeder, supporting transmitting and receiving of radio signals.
External View
This cable is an 1/2" RF cable (50Ω). A DIN connector is mounted on both ends, as shown
in Figure 4-3.

Connections
The cable connection between an RRU and a BBU is as follows:
End A is connected to an optical interface (OPT1, OPT2, or OPT3) on the ZXSDR
R8882 chassis.
End B is connected to an appropriate optical interface of the BBU.
The cable connection between two cascaded RRUs is as follows:
End A is connected to an optical interface (OPT1, OPT2, or OPT3) on a ZXSDR R8882
chassis.
End B is connected to an optical interface (OPT1, OPT2, or OPT3) on the other
ZXSDR R8882 chassis.
4.6 External Monitoring Cable
Function
The external monitoring cable supports the interaction of signals between the ZXSDR
R8882 system and external devices, including the interaction of alarm signals,
RS485/RS422 control signals, and dry contact signals.
