A1471 User ManualIntroductionThis high performance Analog RF Fiber Optic Transmission System converts RFsignals into intensity modulated light to be carried through standard single modeoptical fiber to the Optical Receiver. The Receiver converts the modulated lightback to the original RF signal. Fiber-Span uses high performance opticalcomponents to ensure maximum dynamic range.1 WarningsWarning: Invisible radiation exits from areas labeled “Aperture”A US standard 120V AC 60 Hz to 12VDC power supply powers the units. Useprecautions to prevent electrical shock hazards. Always terminate the RFconnections before applying power to the unit.2 Product overviewThe optical transmission system is comprised of one AC3101-BTR-4 base subrackwith four AC300T and four AC300R modules internally installed and front panelLED power indicator, and four AC3101-BTR-RM remote Nema Type 4Xenclosures. Each AC3101-BTR-RM contains one AC106 fiber optic transceiver,one FS-LNA1 low noise amplifier, one FS-PA1 power amplifier, one band passfilter, one low pass filter, and one removable 3dB RF attenuator. In addition, boththe subrack and remote units are supplied with an external power supply andlocking cable, which is interchangeable between units of all types.3 InstallationThis transmission system is designed to be setup by professionalcommunications systems installers. System installers should be from, apublic utility, Nuclear Power Plant, or other qualified personnel.The AC3101-BTR-4 subrack is compatible with a standard 19” 1U rack, andmounts on the rack system using standard hardware and practices. AC3101-BTR-RM remote units should be mounted securely using the four enclosure mountingholes provided. AC3101-BTR-RM units should be mounted flat against a wall orcolumn with the long dimension perpendicular to the floor, hinge on the left,

Connect RF and Optical cables before powering up the modules.Connect fiber optic and RF cables as shown below:A2-4aBTR-700 C6-4aBTR-700 C6-8aBTR-700A2-7bBTR-700Facility 1 Facility 2C6-4aA2-4a C6-8aA2-7b C6-4aA2-4a C6-8aA2-7bRemote 1Remote 3Remote 2Remote 4Opt in Opt in Opt in Opt inOpt out Opt out Opt out Opt outExample of ChannelAssignments:A2-4a = A2 Band, Group 4aFiber Optic CablesRF CablesCLA-1Antenna(Blue) TypicalCLA-3Antenna(Red) TypicalSystem Connection Diagram
A1471 User ManualSetup Program BTR-700 Radios and Beltpacks to frequency groups asindicated in System Connection Diagram. See appendix for BTR frequency chartsfor reference. Set the transmitter RF output power for 100 mW. Be sure toterminate the transmitter RF output before power up.To install fiber optic cable to subrack, remove dust covers, clean opticalconnector, align FC/APC connector key and hand tighten. Do not overtighten.To install fiber optic cable to remote units, see attached fiber installation guide.This guide is also provided on the inside lid label of remote units. Clean opticalconnectors prior to installation.To power up subrack and remote units, unsnap dust cover from power supplyreceptacle and insert the provided power supply plug into the receptacle on theunit. Align plug key, and push plug into receptacle. Tighten the locking ring on plug.Power supplies are interchangeable between all units.To remove optional 3dB attenuator from remote unit, refer to attached remoteunit diagram, or remote unit lid diagram. Remove power from remote unit. With3/16” open end crescent wrench, loosen both ends of 3 dB attenuator fromattached RF cable and power amplifier. Remove attenuator, and directly re-connectRF cable to power amplifier.Installation VerificationRemote Transceivers To verify correct installation: LED’s L,M,N,O,and P shouldall be green when the system is in normal operation. See Remote Transceiverdiagram for LED functions. This system has been designed to provide 20 mW ofRF power at each remote when the BTR-700 set to 100 mW. RF output power canbe increased 3dB by removing the optional 3dB attenuator. See RemoteTransceiver diagram for the location. Power must be removed from the unit beforethis option is exercised.Keep transmit and receive antennas separated 3 feet minimum. One antennaextension kit is provided for each Remote Transceiver. DO NOT INSTALLHARDWARE (ANTENNA OR POWER AMPLIFIER) TO BOOST RF OUTPUTPOWER. THIS MAY VIOLATE FCC RULES AND REGULATIONS.Base Station Transceiver To verify correct installation: Verify system isconnected as shown in System Connection Diagram before power up. On the frontpanel a Green LED will indicate that power is present in normal operation.4 MaintenancePrecaution: All units should be handled observing ESD precautions to preventelectro-static damages. Disconnect power prior to opening remote units.
A1471 User ManualFC/APC and RF connections should be cleaned using optics grade Isopropylalcohol prior to coupling.CAUTION: Do not over-tighten connections. Connections should be hand-tightened plus 1/4 turn.5 Company InformationFiber-Span designs and manufactures fiber optic modules used in the transmissionand distribution of RF and wireless signals. Fiber-Span’ s fiber optic transmitters,receivers and transceivers are widely used in wireless and RF systems worldwideby wireless systems OEM’s, systems integrators and military systems designers tocapitalize on the inherent advantages of fiber. Fiber has extremely low RFattenuation (< 1dB/km), very high bandwidth, immunity to EMI, no signal egress,flat broadband delay characteristics plus a cable design that is light weight andsmall size.Fiber-SpanOne Possumtown RoadPiscataway, NJ 08854732.564.9000732.564.1990 FAXInternethttp://www.fiber-span.comtechinfo@fiber-span.comAttached Drawings / Documents:Remote Unit Component DiagramRemote Unit Fiber Installation Guide700-800_frequency_PlanBTR-TR-700-800_Freq_Info
