Connecting Multiple Fusion Main Hubs To A Duplex Repeater Or Bts - ADC InterReach Fusion Installation, Operation And Reference Manual

D-620610-0-20 Rev D
Connecting Multiple Fusion Main Hubs to a Duplex 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.)
• 2 N-male to N-male coaxial jumper cables to connect each Fusion Main Hub's RF
Band to the power combiner/splitters
• 1 circulator
• 1 N-male to N-male coaxial jumper cable between each circulator and the repeater
or base station
• 1 N-male to N-male coaxial jumper cable between each circulator and power com-
biner/splitter
Procedure:
Connect the circulator to the repeater or base station using one N-male to N-male

coaxial jumper cable.
Connect each power combiner/splitter to the circulator using one N-male to

N-male coaxial jumper cable per combiner/splitter.
Connect the power combiner/splitter to the Hubs using N-male to N-male coaxial

NOTE: Connections should not cross Bands. For example, all Band 1 connections
should be made to the same hybrid power combiner/splitter connected to the repeater
BTS that matches the Band 1 frequency.
Check Hub LEDs.
