(6.56 ft), 3 m (9.84 ft), 4 m (13.12 ft), 6 m (19.68 ft), or 10 m (32.81 ft) long. A variable-length
RF jumper used by an RRU has a maximum length of 10 m (32.81 ft).
7.10 RRU AISG Multi-Wire Cable
An RRU AISG multi-wire cable is 5 m (16.4 ft.) long. It connects an RRU and a remote control
unit (RCU) to transmit control signals from a base station to the RET antenna. When the RRU
is connected to the RET antenna, an AISG multi-wire cable transmits RS485 signals.
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.
