2.3 RRU Cables

The RRU cables include the PGND cable, power cable, AISG multi-wire cable, AISG extension
cable, CPRI optical cable, RF jumper, and alarm cable.
2.3.1 PGND cable of the RRU
The PGND cable ensures the grounding of the RRU.
2.3.2 Power Cable of the RRU
The RRU uses a shielded -48 V DC power cable. The cable feeds external -48 V DC power to
the RRU.
2.3.3 CPRI Optical Cable
This describes the CPRI optical cable. It connects the BBU3836 to the RRU and transmits CPRI
signals between them.
2.3.4 AISG Multi-Wire Cable of the RRU/SRXU
The five-meter-long AISG multi-wire cable connects the RRU/SRXU to the Remote Control
Unit (RCU). If both RRU and SRXU are installed, the AISG multi-wire cable only connects the
SRXU and the RCU. This cable is optional.
2.3.5 AISG Extension Cable of the RRU/SRXU
When the distance between the RCU and the RRU/SRXU is longer than 5 m, the AISG multi-
wire cable is not long enough to cover the distance. In this case, the AISG extension cable is
used. The AISG extension cable is 15 m long.
