I. INTRODUCTION PURPOSE OF MANUAL: The purpose of this manual is to outline the installation, describe the operation, and assist in the maintenance and trouble-shooting of the CELLULAR Fiber Optical Extender, Model 51483-C. MANUAL OUTLINE Section II covers the general specification of the CELLULAR Section II: Fiber Optical Extender. This section outlines the general, mechanical and electrical specifications including the module specifications (sub-assemblies).

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.

III. INSTALLATION The CELLULAR Fiber Optical Extender is housed in a 19” Rack Mount 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 NType Connector on the CELLULAR DONOR front panel RF PORT. The RF cable from Server Antenna to the SERVER UNIT is connected to female NType Connector on the CELLULAR SERVER front panel RF PORT.

IV. OPERATION OF EQUIPMENT The CELLULAR Fiber Optical Extender requires no operator settings for operation. It is designed for unattended operation.
PAGE 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.

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.

VII. TROUBLESHOOTING This Troubleshooting Procedure has been developed for the use of a trained technician with knowledge of troubleshooting methodology in order to isolate faults to the unit level. SERVER UNIT Problem 1. Power LED is off Solution a) Check Fuse, if fuse is ok go to next step. b) Check Power Supply 110VAC input, if 110VAC is present, go to next step. c) Check Power Supply +12VDC output. If +12 volt is not present, replace the Server Unit. a) Replace the Server Unit. 2.

DONOR UNIT Problem 1. Power LED is off Solution a) Check Fuse, if fuse is ok go to next step. b) Check Power Supply 110VAC input, if 110VAC is present, go to next step. c) Check Power Supply +12VDC output. If +12 volt is not present, replace the Donor Unit. a) Replace the Donor Unit. 2. PWR LED is off (F/O TRX INDICATORS) a) Replace the Donor Unit. 3. LASER LED is off (F/O TRX INDICATORS) a) to Problem 8. 4. F/O LED is off (F/O TRX INDICATORS) 5.
