RAU Overview
Downlink Path: The RAU receives downlink IF signals from a Fusion Hub using 75 Ohm CATV cable. It converts the sig-
nals to RF and sends them to a passive RF antenna using 50 Ohm coaxial cable. Also, the RAU receives configuration
information from the Fusion Hub using the 75 Ohm CATV cable.
Fusion Main Hub
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 Hub using 75 Ohm CATV cable. Also, the RAU sends its status information to the
Fusion Hub using CATV cable.
The RAU receives 54VDC power from the Fusion Hub port through the 75 Ohm CATV cable center pin.
