RFU Cable Connection
RFU-D, RFU-D-HP, RFU-E, and RFU-S can be connected to the IP-20F IDU via a standard
CAT-5e or preferably CAT-6/6a cable, with RJ-45 connectors on the RFU and an RJ-45
connector on the IDU. They can also be connected to the IDU over optical fiber cables
via the optical (SFP) RFU interface on the IDU.
For an RFU-D, RFU-E, or RFU-S connecting to an electrical RFU interface, the cable can
carry both the data and the DC power required for the RFU. For configuration
instructions, refer to the
User Guide for FibeAir IP-20F, IP-20G, and IP-20GX
.
For an RFU-D, RFU-E, or RFU-S connecting to an optical RFU interface, and for an RFU-
D-HP connecting to either an electrical or an optical RFU interface, an external DC
power cable is required to supply power to the RFU.
