Preparing for System Installation
Repeater Installed between lightning arrestor/surge suppressor and Hub; N-male to N-male
coaxial cable. The Repeater must be a UL listed product.
Attenuator Installed between the circulator and the Hub downlink port to prevent overload.
Optionally, it may be installed between the uplink port and the circulator.
Circulator or Duplexer Installed between the repeater and the Hub uplink and downlink ports
Base Station-to-Fusion Configuration (for each Fusion Band)
Base Station Installed, inspected; verify RF power (see tables in Section 6.3 on page 6-4);
N-male to N-male coaxial cable
Attenuator Attenuation may be required to achieve the desired RF output at the RAU, and the
desired uplink noise floor level
Circulator or Duplexer When using a duplex BTS: Installed between the BTS and the Hub uplink and
downlink ports. Not used with a simplex BTS
Connecting Multiple Fusion Main Hubs Together
5-port Alarm Daisy-Chain Cable
(PN 4024-3)
For contact alarm monitoring of fault and warning alarms. Used to feed the alarms
from multiple Fusion Main Hubs into a BTS or MetroReach Focus. N.C. Opera-
tion.
Cabling
Coaxial: repeater, base station,
Smart Source to Fusion Main
Hub
Coax approved; N-type male connectors.
Coaxial: RAU to passive
antennas
Use low-loss cable; N male connector; typical 1 m (3.3 ft) using RG142 coaxial
cable.
Fiber: Main Hub to Expansion
Hubs
SC/APC (angle-polished) male connectors for entire fiber run (can use SC/APC
pigtails, PN 4012SCAPC-10 for MMF or 4013SCAPC-10 for SMF);
Use jumper fiber cables for collocated Main and Expansion Hubs (3 m/10 ft.):
Multi-mode: PN 401SCAPC-10
Single-mode: PN 4018SCAPC-10
Distance limited by optical loss of 3 dB
Multi-mode up to 500 m (1640 ft.)
Single-mode up to 6 km (19,685 ft.)
CATV TIA-570-B approved; centerpin F male connectors. CATV connectors must be
connected to the shield at both ends. The RAU will be damaged if it is mis-wired.
Tie-off cables to avoid damaging the connectors because of cable strain.
Fusion Expansion Hub to RAUs • Minimum: 0 meters (0 ft)
• Maximum: RG-59: 150 meters (472 ft) *
RG-8: 170 meters (558 ft)
RG-11: 275 meters (902 ft)
