5GENERAL SYSTEM OVERVIEW:The AeroComm, Inc. Fiber Optic Booster Amplifier (Model#51483-C) can beused where CELLULAR Carrier Service is required but not accessible due to long ordifficult coaxial cable runs. It eliminates costly construction using coaxial cable. TheAeroComm, Inc. Model#51483-C converts the Carrier RF signal, enabling the use ofFiber Optic Cable which is easily routed to inaccessible areas and has much lower loss,where it is then reconverted back to Carrier RF signal.

12IV. OPERATION OF EQUIPMENTThe CELLULAR Fiber Optical Extender requires no operator settings foroperation. It is designed for unattended operation.The following is all that is necessary for operation:# Install# Connect# Turn-On# Watch LED
13V. MAINTENANCE SCHEDULEThe CELLULAR Fiber Optical Extender is designed for unattended operationrequiring minimal maintenance. General maintenance consists of equipment inspectionand operational tests. Periodical equipment tune-up and alignment is recommended.CABLE INSPECTIONS:The external and internal cables and connectors should be checked forindication of corrosion.ENCLOSURE INSPECTIONS:The interior of the enclosures should be inspected for evidence ofcondensation.LED INSPECTIONS:DONOR UNIT# POWER LED: ON# F/O TRX INDICATORSF/O LED: ONPWR LED: ONLASER LED: ON# ALARM INDICATORSF/O LED: GREENPWR AMP LED: OFFLNA2 LED: OFFLNA1 LED: OFF# COMM PORTNormal: Closed (Pin1 & Pin2)Fault: Open (Pin1 & Pin2)SERVER UNIT# POWER LED: ON# F/O TRX INDICATORSF/O LED: ONPWR LED: ONLASER LED: ON# ALARM INDICATORSF/O LED: GREENPWR AMP LED: OFFLNA2 LED: OFFLNA1 LED: OFF# COMM PORTNormal: Closed (Pin1 & Pin2)Fault: Open (Pin1 & Pin2)The performance of operations testing is recommended to be done semi-annually.Operational testing will indicate equipment status, determining if an alignment isnecessary.
14VI. THEORY OF OPERATIONThe CELLULAR Fiber Optical Extender has two channels, one is Down Linkfrequencies from 869MHZ to 894MHZ, and the other is UP Link frequencies from824MHZ to 849MHZ. Both Up Link and Down Link signals are converted from RFsignals to optical signals then through the fiber optical cable to the far end and convertedback 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 tolong 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 hasmuch lower loss, where it is then reconverted back to Carrier RF signal.Caution: The user that changes or modifications not expressly approved by the partyresponsible for compliance could void the user’s authority to operate the device (CFR 47section 15.2)NOTE: This equipment has been tested and found to comply with the limits for a ClassA digital device, pursuant to part 15 of the FCC Rules. These limits are designed toprovide reasonable protection against harmful interference when the equipment isoperated in commercial environment. This equipment generates, uses and can radiateradio frequency energy and, if not installed and used in accordance with the instructionmanual, may cause harmful interference to radio communications. Operation of thisequipment in a residential area is likely to case harmful interference in which case theuser will be required to correct the interference at this own expense.
