2.3.3 AISG Multi-Wire Cable of the RRU3804/SRXU
The five-meter-long AISG multi-wire cable connects the RRU3804/SRXU to the Remote
Control Unit (RCU). If both RRU3804 and SRXU are installed, the AISG multi-wire cable only
connects the SRXU and the RCU. This cable is optional.
2.3.4 AISG Extension Cable of the RRU3804/SRXU
When the distance between the RCU and the RRU3804/SRXU is longer than 5 m, the AISG
multi-wire cable is not long enough to cover the distance and the AISG extension cable is used.
The AISG extension cable is 15 m long.
2.3.5 BBU3806-RRU/SRXU CPRI Optical Cable
The CPRI optical cable transmits CPRI signals between BBU3806 and RRU3801C, between
BBU3806 and RRU3804, and between RRU3804 and SRXU.
2.3.6 BBU3806C-RRU/SRXU CPRI Optical Cable
The CPRI optical cable transmits CPRI signals between BBU3806C and RRU3801C, between
BBU3806C and RRU3804, and between RRU3804 and SRXU.
2.3.7 RF Jumper of the RRU3804/SRXU
The RF jumper of the RRU3804/SRXU is of two types: antenna jumper and interconnect jumper.
The interconnect jumper is optional, depending on the site configuration.
2.3.8 Boolean/RS485 Input Cable of the RRU3804
The cable transmits the 2-channel Boolean alarm signals and 1-channel RS485 signals from
external devices to the RRU3804. Thus, the external signals are monitored.
2.3.1 PGND Cable of the RRU3804
The PGND cable ensures the grounding of the RRU3804.
Appearance
The green and yellow PGND cable is a single cable with a cross-sectional area of 16 mm
2
. Both
ends of the cable are OT terminals. If you prepare the cable by yourself, it is recommended to
use a copper-based cable with a minimum cross-sectional area of 16 mm
2
.
Figure 2-6 shows the PGND cable.
Figure 2-6 PGND cable
Both ends of the PGND cable need to be made into OT terminals on site. You can determine the
color of the cable and whether to use 2-hole terminals according to local standards.
Figure 2-7 shows the 2-hole terminal.
