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.
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.
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.
Setup Program BTR-700 Radios and Beltpacks to frequency groups as indicated in System Connection Diagram. 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.
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. 5 Company Information Fiber-Span designs and manufactures fiber optic modules used in the transmission and distribution of RF and wireless signals.

12/17/01 700/800 Systems Frequency Selection Rules 1. Frequency Spacing……………..…Keep all BTR/TR receive and transmit frequencies at least 300kHz away from each other, >400kHz preferred. Both the transmitters and receivers should be at least 400kHz away from other RF equipment. 2. IM Products………….…………… 2 transmitter 3rd orders by at least 100kHz (200kHz preferred) 3 transmitter 3rd orders by at least 50kHz (100kHz preferred) 2 transmitter 5th orders by at least 50kHz (100kHz preferred) 3.
