FUSION WIDEBAND MAIN HUB OVERVIEW
The Fusion Wideband Main Hub (shown in Figure 8) distributes up to three individual (Band 1, 2,
and 3) downlink RF signals from a Base
Station, repeater, or FlexWave Focus system to up to four
Expansion Hubs, which in turn distribute the signals to up to 32 Remote Access Units. The Main
Hub also combines uplink signals from the associated Expansion Hubs.
Fusion Wideband is a multi-band sy
s
tem. One RF source (Band 1 or RF1) goes to the 60 MHz band
and the other RF source (Band 2 or RF2) goes to the 75 MHz band. Band 3 (or RF3) goes to a 25
MHz sub-band of the 60 MHz band and is functional only with the following RAUs:
800/850/1900, 700/AWS, 700/700 (Upper C) MIMO, 700/700 (Lower ABC) MIMO, 700
ABC/AWS HP/AWS HP, 700 UC/AWS HP/AWS HP, and 850/1900 HP/AWS HP RAU. The system
installs in a 19”equipment rack and is usually co-located with the RF source in a
telecommunications closet.

Main Hub.
NOTE: The Fusion Wideband One Port Main Hub (PNs: FSN-W1-MH-2-1P, FSN-W2-MH-3-1P,
FSN-W3-MH-1P, FSN-W4-MH-1P, and FSN-W5-MH-1P) 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, or 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 converts
the signals to IF then to RF and sends them to the respective Band1, 2, or 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.
