Installing the RRU Cables
RCU
z
When the length of the AISG multi-wire cable
between the RRU and the RCU is not enough, you
can choose the optional AISG extended cable
between the RRU and the RCU.

If the coaxial cable is used for the RET antenna
when the STMA or Smart Bias-Tee (SBT) is used,
the OOK signals are required. Therefore, the port for
the RET antenna needs to use the ANT_TX/RXA
port.
