IDU-RFU Connection
An RFU-S, RFU-D, and RFU-D-HP can be connected to an PTP 820F IDU via
a standard CAT-5e or CAT-6 cable, with RJ-45 connectors on the RFU and
one of the RJ-45 RFU interfaces on the PTP 820F. They can also be
connected to the IDU over optical fiber cables via one of the optical (SFP)
RFU interfaces on the IDU.
For an RFU-S, or RFU-D connecting to an RJ-45 RFU interface, the cable
carries both the data and the DC power required for the RFU.
For an RFU-S, or RFU-D connecting to an SFP RFU interface, and for an
RFU-D-HP connecting to either an RJ-45 or an SFP RFU interface, an
external DC power cable is required to supply power to the RFU.
Power Consumption Specifications
The following table shows the maximum power consumption for PTP 820F IDU and supported
RFUs. The maximum power consumption for the entire system is the sum of the IDU and the RFUs
connecting to it.
