Fiber-Span Installation Guide and User Manual AC3101-BTR-4 Fiber Optic Transmission System 1U, 19” Subrack Enclosure AC3101-BTR-RM Fiber Optic Transmission System NEMA Type 4X Enclosure Fiber-Span One Possumtown Road Piscataway, NJ 08854 732.564.9000 732.564.1990 Fax www.fiber-span.com A1471 User Manual Introduction This high performance Analog RF Fiber Optic Transmission System converts RF signals into intensity modulated light to be carried through standard single mode optical fiber to the Optical Receiver. The Receiver converts the modulated light back to the original RF signal. Fiber-Span uses high performance optical components to ensure maximum dynamic range. Warnings Warning: Invisible radiation exits from areas labeled “Aperture” A US standard 120V AC 60 Hz to 12VDC power supply powers the units. Use precautions to prevent electrical shock hazards. Always terminate the RF connections before applying power to the unit. Product overview The optical transmission system is comprised of one AC3101-BTR-4 base subrack with four AC300T and four AC300R modules internally installed and front panel LED power indicator, and four AC3101-BTR-RM remote Nema Type 4X enclosures. Each AC3101-BTR-RM contains one AC106 fiber optic transceiver, one FS-LNA1 low noise amplifier, one FS-PA1 power amplifier, one band pass filter, one low pass filter, and one removable 3dB RF attenuator. In addition, both the subrack and remote units are supplied with an external power supply and locking cable, which is interchangeable between units of all types. Installation This transmission system is designed to be setup by professional communications systems installers. System installers should be from, a public utility, Nuclear Power Plant, or other qualified personnel. The AC3101-BTR-4 subrack is compatible with a standard 19” 1U rack, and mounts on the rack system using standard hardware and practices. AC3101-BTRRM remote units should be mounted securely using the four enclosure mounting holes provided. AC3101-BTR-RM units should be mounted flat against a wall or column with the long dimension perpendicular to the floor, hinge on the left, A1471 User Manual enclosure latch on right, and vent at top. Provide adequate airflow to the lower right and top vents. Connect RF and Optical cables before powering up the modules.

See appendix for BTR frequency charts for reference. Set the transmitter RF output power for 100 mW. Be sure to terminate the transmitter RF output before power up. To install fiber optic cable to subrack, remove dust covers, clean optical connector, 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 optical connectors prior to installation. To power up subrack and remote units, unsnap dust cover from power supply receptacle and insert the provided power supply plug into the receptacle on the unit. 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 remote unit diagram, or remote unit lid diagram. Remove power from remote unit. With 3/16” open end crescent wrench, loosen both ends of 3 dB attenuator from attached RF cable and power amplifier. Remove attenuator, and directly re-connect RF cable to power amplifier. Installation Verification Remote Transceivers To verify correct installation: LED’s L,M,N,O,and P should all be green when the system is in normal operation. See Remote Transceiver diagram for LED functions. This system has been designed to provide 20 mW of RF power at each remote when the BTR-700 set to 100 mW. RF output power can be increased 3dB by removing the optional 3dB attenuator. See Remote Transceiver diagram for the location. Power must be removed from the unit before this option is exercised. Keep transmit and receive antennas separated 3 feet minimum. One antenna extension kit is provided for each Remote Transceiver. DO NOT INSTALL HARDWARE (ANTENNA OR POWER AMPLIFIER) TO BOOST RF OUTPUT POWER. THIS MAY VIOLATE FCC RULES AND REGULATIONS. Base Station Transceiver To verify correct installation: Verify system is connected as shown in System Connection Diagram before power up. On the front panel a Green LED will indicate that power is present in normal operation. Maintenance Precaution: All units should be handled observing ESD precautions to prevent electro-static damages. Disconnect power prior to opening remote units. A1471 User Manual FC/APC and RF connections should be cleaned using optics grade Isopropyl alcohol prior to coupling. CAUTION: Do not over-tighten connections. Connections should be handtightened plus 1/4 turn. Company Information Fiber-Span designs and manufactures fiber optic modules used in the transmission and distribution of RF and wireless signals. Fiber-Span’ s fiber optic transmitters, receivers and transceivers are widely used in wireless and RF systems worldwide by wireless systems OEM’s, systems integrators and military systems designers to capitalize on the inherent advantages of fiber. Fiber has extremely low RF attenuation (< 1dB/km), very high bandwidth, immunity to EMI, no signal egress, flat broadband delay characteristics plus a cable design that is light weight and small size.
