7.11 RRU AISG Extension Cable
When the distance between an RRU and an RCU is longer than 5 m (16.4 ft.), an AISG multi-
core cable cannot connect the RRU and the RCU because it is not long enough. In this case, an
AISG extension cable is used to extend the AISG multi-core cable for transmitting RS485
signals.
