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 4010SCAPC-10
Single-mode: PN: 4018SCAPC-10
Distance limited by optical loss of 3 dB:
Multi-mode: up to 1.5 km (4,921 ft);
Single-mode: up to 6 km (19,685 ft)
Cat-5E/6 ScTP:
TIA/EIA 568-A approved; shielded RJ-45 male connectors. ScTP cable must be
screened and it must be grounded at both connector ends
Tie-off cables to avoid damaging the connectors because of cable strain
Expansion Hub to RAUs
• Minimum: 10 meters (33 ft)
• Recommended Maximum: 100 meters (328 ft)
Cat-5E/6 ScTP: Expansion Hub
to Cat-5 Extender to RAU**
Configuring System
PC/laptop running AdminManager
software
Refer to the
AdminManager User Manual
(PN 8810-10)
Miscellaneous
Null modem cable
Female connectors; Main Hub to a PC/laptop that is running the AdminManager
software; local connection
Straight-through cable
Female/male connectors; Main Hub to a modem; remote connection
Cat-5 Extender
Used if Cat-5E/6 run(s) will exceed 100 meters
Dual-Band Diplexer
Used in dual band systems to
combine the output of a low-band RAU and a
high-band RAU to a single
dual band antenna
Distances
Main Hub is within 3–6m (10–20 ft)
of connecting repeater
If longer distance, determine the loss of the cable used for this connection and
adjust the RF signal into the Main Hub accordingly. This can be done by read-
justing the power from the base station, or by changing the attenuation value
between the base station/repeater and the Main Hub
Main Hub is within 3–6m (10–20 ft)
of connecting base station
Main Hub is within correct distance of Expansion Hub(s);
SMF and MMF optical link budget: 3 dB
