7.6.2 Connecting Multiple Fusion Main Hubs to an RF Source
You can use power combiner/splitters as splitters to connect multiple Fusion Main
Hubs in order to increase the total number of RAUs in a system. You can also use
power combiner/splitters to combine base station channels in order to increase the
number of RF carriers the system transports.
Connecting Multiple Fusion Main Hubs to a Simplex Repeater or
BTS
WARNING: Only ADC personnel or ADC-authorized installation per-
sonnel should connect the Fusion Main Hub to a base station or
repeater. Exceeding the maximum input power could cause failure of
the Fusion Main Hub (refer to Section 5.2 on page 5-4 for maximum power spec-
ifications). If the maximum composite power is too high, attenuation is required.
Considerations:
• 2 hybrid power combiner/splitters; one for uplink and one for downlink (2x1 for
two Fusion Main Hubs, 3x1 for three, 4x1 for four, and so on.)
• 1 N-male to N-male coaxial jumper cable between each power combiner/splitter
and the base station
• 2 N-male to N-male coaxial jumper cables between each power combiner/splitter
and each Fusion Main Hub RF Band (either Band 1 or Band 2)
Procedure:
1. Connect the power combiner/splitters to the repeater or base station using N-male
to N-male coaxial jumper cables:
a. From the first power combiner/splitter to the repeater or base station UPLINK
b.
From the second power combiner/splitter to the repeater or base station
DOWNLINK
2.
Connect the power combiner/splitters to the Hubs:
a. From the first Hub’s UPLINK port (Band 1, Band 2, or Band 3) to the first
power combiner/splitter
b. From the first Hub’s DOWNLINK port (Band 1, Band 2, or Band 3) to the sec-
ond power combiner/splitter
c. From the second Hub’s UPLINK port (Band 1, Band 2, or Band 3) to the first
power combiner/splitter
d. From the second Hub’s DOWNLINK port (Band 1, Band 2, or Band 3) to the
second power combiner/splitter
