GENERAL SYSTEM OVERVIEW:
The AeroComm, Inc. Fiber Optic Booster Amplifier (Model#51483-C) can be
used where CELLULAR Carrier Service is required but not accessible due to long or
difficult coaxial cable runs. It eliminates costly construction using coaxial cable. The
AeroComm, Inc. Model#51483-C converts the Carrier RF signal, enabling the use of
Fiber Optic Cable which is easily routed to inaccessible areas and has much lower loss,
where it is then reconverted back to Carrier RF signal.

enclosure. Refer to Figure 1 for the installation block diagram.
RF CABLE CONNECTIONS
! The RF cable from Donor Antenna to the DONOR UNIT is connected to female N-
Type Connector on the CELLULAR DONOR front panel RF PORT.
! The RF cable from Server Antenna to the SERVER UNIT is connected to female N-
Type Connector on the CELLULAR SERVER front panel RF PORT.
FIBER OPTICAL CABLE CONNECTIONS
The FC/APC to FC/APC fiber cables is connected between Donor and Server front panel.
! Donor FO OUT connects to the Server FO IN.
! Donor FO IN connects to the Server FO OUT.
" Caution: The FC/APC Fiber Optic connector is a Keyed connector, if the Key is not

operation. It is designed for unattended operation.
The following is all that is necessary for operation:
# Install
# Connect
# Turn-On
# Watch LED
13
V. MAINTENANCE SCHEDULE
The CELLULAR Fiber Optical Extender is designed for unattended operation
requiring minimal maintenance. General maintenance consists of equipment inspection
and operational tests. Periodical equipment tune-up and alignment is recommended.
CABLE INSPECTIONS:
The external and internal cables and connectors should be checked for
indication of corrosion.
ENCLOSURE INSPECTIONS:
The interior of the enclosures should be inspected for evidence of
condensation.

The performance of operations testing is recommended to be done semi-annually.
Operational testing will indicate equipment status, determining if an alignment is
necessary.

VI. THEORY OF OPERATION
The CELLULAR Fiber Optical Extender has two channels, one is Down Link
frequencies from 869MHZ to 894MHZ, and the other is UP Link frequencies from
824MHZ to 849MHZ. Both Up Link and Down Link signals are converted from RF
signals to optical signals then through the fiber optical cable to the far end and converted
back to RF signals. The AeroComm, Inc. Fiber Optic Booster Amplifier (Model#51483-
C) can be used where CELLULAR Carrier Service is required but not accessible due to
long or difficult coaxial cable runs. It eliminates costly construction using coaxial cable.
The AeroComm, Inc. Model# 51483-C converts the Carrier RF signal to optical signals,
enabling the use of Fiber Optic Cable which is easily routed to inaccessible areas and has
much lower loss, where it is then reconverted back to Carrier RF signal.
Caution: The user that changes or modifications not expressly approved by the party
responsible for compliance could void the user’s authority to operate the device (CFR 47
section 15.2)
NOTE: This equipment has been tested and found to comply with the limits for a Class
A digital device, pursuant to part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interference when the equipment is
operated in commercial environment. This equipment generates, uses and can radiate
radio frequency energy and, if not installed and used in accordance with the instruction
manual, may cause harmful interference to radio communications. Operation of this
equipment in a residential area is likely to case harmful interference in which case the
user will be required to correct the interference at this own expense.
