IDU-RFU Cable Connection
RFU-D, RFU-D-HP and RFU-S can be connected to the PTP 820F 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, 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
PTP 820F, PTP 820G.
For an RFU-D, 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.
