Always terminate the RF connections before applying power to the unit. Page 3 of 13 Rev 01 5-DEC-06 Fiber Optic RF Repeater System 3 Product Overview Fiber-Span provides product to enable RF signal to be distributed via optical fiber cable. RF signal sources can be used from over the air (OTA) from a Radio Base Station (BS), OTA from handheld devices, or directly from a BS radio. RF signals are converted to modulated light for transport through optical fiber media to remote locations. Modulated light is converted back to the original RF signal where it is processed through filtering and amplification to allow the RF signal to be re-radiated in the remote location. In a bi-directional RF system, the process is the same resulting in remote RF signals that are sent back simultaneously. Fiber-Span product functionality OTA system - RF signals from a remote base station are interchanged usually from a roof top antenna that is connected to an Integrated Head-end Unit (IHU). The IHU receives downlink signals from the base station and sends uplink signals back to the base station. The IHU distributes signals via fiber optics to remote location and also is capable of simultaneously interfacing with a Distributed Antenna System (DAS) for short range RF distribution. Figure 2. Typical OTA Optical RF distribution System Local Base Station System – Signals from a local base station interface to optical distribution equipment through Base Station Units (BSU), or directly to a Fiber Transceiver Unit (FTU). The BSU sometimes interfaces the Base Station to the FTU. The BSU is used to passively condition RF levels or serve as RF filters when applicable. The FTU performs bi-directional optical-RF conversions. Optical signals are sent to the Remote Repeater Unit (RRU). The RRU is designed for use as a remote end of a bi-directional RF distribution system. The RRU RF port works with a direct connected RF antenna or to a Distributed Antenna System (DAS). The RRU is connected via optical fibers to a Fiber Transceiver Unit (FTU) to complete a point to point RF link.

FS31X Series Fiber Optic RF Repeaters 806-941 MHz Integrated Headend Unit, or remote Optical Repeater DS3102-8-05 v.1 RF ON FIBER ® Signal Distribution products for In-building coverage extension applications. FEATURES: • Fully Integrated Headend Configuration • Designed Specifically for Off-Air applications • RF Power Options: 1/2, 1, 5, 10, 20 Watt • Low Noise & High Dynamic Range • RF & Alarm Monitoring over same fiber • Support for up to 8 Remote Units • Battery Back-up Options Fiber-Span’s FS31X Series is a first of its kind in the industry to fully integrate the traditional Bi-directional Amplifier (BDA), combining/splitting sub-system and fiber optic transceivers all into a single wall-mount enclosure. Fiber-Span’s FS31X product line is designed to be the most cost-effective Fiber Optic solution for off-air coverage extension applications. This integrated approach is easy to implement and can be configured to support up to 8 Remote Repeater Units (RRU). In addition to the fiber optic interface, all FS31X series Headend units feature separate transmit and receive RF ports for compatibility with conventional coaxial cable Distributed Antenna Systems (DAS). A separate FS31DU duplexer unit is available for applications where transmit and receive signals must be duplexed onto a common coaxial cable distribution system. Each RRU can be configured with a 1/2, 1, 5, 10 or 20 Watt downlink amplifier, giving system designers the flexibility to “size-up” the remote unit for optimum performance over a single antenna distribution system or a network of distributed antennas.
