3.8 AISG Extension Cable
When the distance between an RRU and an AAU is longer than 5 m (16.4 ft), an AISG multi-
wire cable is not long enough to connect the RRU and the AAU. In this case, an AISG extension
cable is used to extend the AISG multi-wire cable. An AISG extension cable is 15 m (49.21 ft).
