When the distance between the RRU and the RCU is more than 5 m, an AISG multi-wire cable
is not long enough to connect the RRU and RCU. In this case, the AISG extension cable is used
to extend the AISG multi-wire cable for transmitting RS485 signals.

The AISG extension cable has a standard AISG male connector on one end and a standard AISG
female connector on the other end, as shown in
