Chapter 3: Connecting the Data and Power Cables

Chapter 3:
Cables
RFU-E is connected to the 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 connection on the IDU.
When using a CAT-5e or CAT-6 cable, the cable can carry both the data and the DC power required for the RFU-E.
The CAT-5e or CAT-6 cable is connected to P1.
When using an optical fiber cable, an external DC power cable is required to supply power to the RFU. The DC
power cable is connected to P1 and the optical fiber cable is connected to P2.
Note
P3 and P4 are reserved for future use.
