Figure 3-2 shows a detailed view of the major RF and optical functional blocks of the 
Main Hub.

NOTE: The Fusion Wideband One Port Main Hub (PN: FSN-W1-MH-1P 
and FSN-W2-MH-1P) configuration is a cost reduced version of the Fusion 
Wideband Main Hub and supports only one Expansion Hub (up to 8 RAUs).

Downlink Path: The Main Hub receives up to 3 individual (Band1, 2, and 3) downlink RF signals from a base station, 
repeater, or FlexWave Focus system using 50 Ohm coaxial cable. It converts the signals to IF then to optical and sends them 
to up to four Expansion Hubs using fiber optic cable.

The Main Hub also sends OA&M communication to the Expansion Hubs using the fiber optic cable. The Expansion Hubs, in 
turn, communicate the OA&M information to the RAUs using CATV cable.

Uplink Path: The Main Hub receives uplink optical signals from up to four Expansion Hubs using fiber optic cables. It con-
verts the signals to IF then to RF and sends them to the respective Band1, 2, and 3 base station, repeater, or FlexWave 
Focus system using 50 Ohm coaxial cable.

The Main Hub also receives status information from the Expansion Hubs and all RAUs using the fiber optic cable.
