Downlink Path: The RAU receives downlink IF signals from a Fusion Wideband Hub using 75 Ohm CATV cable. It con-
verts the signals to RF and sends them to a passive RF antenna using 50 Ohm coaxial cable. Also, the RAU receives con-
figuration information from the Fusion Wideband Hub using the 75 Ohm CATV cable.
Uplink Path: The RAU receives uplink RF signals from a passive RF antenna using 50 Ohm coaxial cable. It converts the
signals to IF and sends them to a Fusion Wideband Hub using 75 Ohm CATV cable. Also, the RAU sends its status infor-
mation to the Fusion Wideband Hub using CATV cable.
The RAU receives 54VDC power from the Fusion Wideband Hub port through the 75 Ohm CATV cable center pin.
