Fusion SingleStar Hub
The Fusion SingleStar Hub interfaces between two individual RF sources (being base
station, repeater, or MetroReach Focus system) and up to eight Remote Access Units.
The Fusion SingleStar is a multi-band system. One RF source (Band 1 or RF1) goes
to the 35 MHz band and the other RF source (Band 2 or RF2) goes to the 75 MHz
band. The system installs in a 19" equipment rack and is usually collocated with the
RF source in a telecommunications closet.
• Downlink Path
The Fusion SingleStar Hub receives downlink RF signals from each RF source
(RF1, RF2) using coaxial cable. It converts the signals to IF and sends them to up
to eight RAUs using CATV cable. The Hub also sends OA&M communication to
the RAUs using the CATV cable.
• Uplink Path
The Fusion SingleStar Hub receives uplink IF signals from up to eight RAUs using
CATV cable. It converts the signals to RF and sends them to an RF source (RF1,
RF2) using coaxial cable. The Hub also receives status information from the RAUs
using the CATV cable.
Figure 3-1 shows a detailed view of the major RF and functional blocks of the Hub.
