OVERVIEW: The FBDA is an interface unit between optical signals carrying RF information, and RF antennas covering a defined user area. The system consists of uplink path and downlink path and an additional uplink path for diversity. The uplink path receives RF signals from the Mobile antenna amplifies them and the Rfiber+ converts them to optical signals. These optical signals are sent to the BTS. The downlink path receives optical signals from the BTS to the Rfiber+, converts them to RF signals and amplifies these signals using a high power amplifier. The Mobile antenna transmits these RF signals. A duplexing filter separates the frequencies of uplink path from the downlink path enabling the use of the same antenna for receiving and transmitting. The FBDA provides about 46 dB RF gain in both directions. Both optical signals for Uplink and Downlink are carried on a single fiber using WDM. Downlink gain can be adjusted using a trim pot on the Rfiber+ front panel for proper output power. Uplink gain can be adjusted by 16 dB continuous trim pot. The downlink path uses a 50 Watt power amplifier while the uplink uses an AGC amplifier to drive the uplink F/O transmitter. The AGC is set to 0 dBm, which is the max power required by the F/O transmitter. For diversity reasons there is an additional Uplink path consisting of Cavity band pass filter, AGC amplifier, and Fiber optic transmitter. The optical signal of this path is transferred via an additional fiber to the base station.

COMPONENTS DESCRIPTION: 2.1 DUPLEXER(x2) The duplexer serves to frequency separate uplink signals from downlink signals. The duplexer has sharp out of band attenuation for better isolation between the receiving and transmitting paths and for better rejection of interfering signal in the air. In the Diversity path only the Rx part of the duplexer is used. 2.2 UPLINK AMPLIFIER(both Rx pathes) The uplink amplifier is a low noise, 45dB gain unit. The amplifier contains AGC control circuitry. When a high power signal is received the automatic level control detects it and reduces the gain so that the output power of the amplifier is constant. The AGC function limits the signal at the Fiberoptic transmitter input when high power signals are received while keeping high gain when low power signals are received. The LED on the amplifier illuminates when the power output of the amplifier exceeds the AGC power set limit (when the AGC is either ON or OFF). The Switch on the RF amplifier enables the AGC function. If the AGC is disabled then the amplifier gives maximum gain for any input. The AGC level is factory set to 0 dBm and AGC is set to ON, to prevent high power damage at the Rfiber+ input. 2.3 50 WATT DOWNLINK POWER AMPLIFIER This is the downlink power amplifier. It can drive 40 dBm composite power to the MOBILE antenna. A thermostat attatched to this amplifier turns on TEMP alarm when the temperature exceeds 80° C. 2.4 Fiberoptic to RF transceiver The RFiber+ TM product is a transceiver that includes a transmitter and receiver unit. The transmitter converts the RF signals into light wave signals, which are then sent over fiberoptic cables. The receiver converts light wave signals back to RF The model in use is a wide band product in the 0.08-1 GHz frequency range and it includes a WDM module to enable use of one fiber for Tx and Rx signals.

OVERVIEW: The Fiber optic repeater system is an excellent solution for BTS coverage extension by means of Fiber optic link and remote high power RF head. The system consists of two conversion boxes; - FBIU (Fiberoptic Base Interface Unit) - FBDA (Fiber optic Bi Directional Amplifier) Two fibers, one for main path, uplink and downlink direction and one in diversity uplink direction connect the FBIU to the FBDA. Using fiberoptic cable allows long distance transmission, up to 20 Km. 1.1 FBIU The FBIU is installed near the BTS and is connected to the BTS by RF cables. A Fiberoptic transceiver converts the Downlink RF signals to optical signals and the uplink optical signal to RF. A high power attenuator is used as power adjustment between BTS Tx power and Fiberoptic transceiver requirements. A separate attenuator is used for Rx direction. The Diversity path is connected through Fiberoptic receiver and fixed attenuator to the Diversity receiver.

A Fiberoptic transceiver converts the Downlink optical signals to RF signals and the uplink RF signals to optical signals. A duplexer in the FBDA separates the uplink and downlink signals thus enabling the use of the same antenna for receiving and transmitting. The duplexer has sharp out of band attenuation for better isolation between the receiving and transmitting paths and for reduction of out of band interfering signals. A high power amplifier in the downlink path produces high RF power to the antenna. A LNA (low noise amplifier) is used to drive the uplink signals from the antenna to the Fiberoptic transceiver input to maintain reasonable NF (noise figure) in the uplink path. The FBDA contains a monitoring unit to monitor the operation of the active elements inside the FBDA. Whenever a fault occurs an ALARM signal is sent to the FBIU. For diversity applications the uplink path is duplicated using separate antenna, filter, LNA and Fiberoptic transmitter. Fig. 1 : Fiber-optic REPEATER SYSTEM BLOCK DIAGRAM Mobile ANT.

In case of separate connections for Rx and Tx , the duplexer is not required. 2.2.3 ATTENUATOR Assuming that the output power of BTS is +30dBm, a 30 dB high power external attenuator is required.

The fault LED illuminates when the voltage is beyond the specified limits. b) Monitors the current to each active element and the two fans at the FBDA panel. (The fans for the high power downlink amplifiers are connected directly to the amplifier). If the current is below or above the specified limits then a LED illuminates. c) Monitor the optical receive signal using alarm output of the optical transceiver. d) Provides automatic alarm function. A relay in the monitor box opens whenever any fault occurs or when the power is removed from the FBDA. The relay arms are normally open and close only when no fault occurs. e) Provides self test for the alarm functions. The pushbutton switch on the Monitor unit turns on all the alarm LEDs and opens the relay arms. f) Send summarized alarm signal to the base station via the F/O data port. 2.6 POWER SUPPLY This is a high efficiency dual switching power supply providing +28 VDC at over 6 Amp for the power amp and +15VDC for other elements.

Maximum Permissible Exposure (MPE) Compliance Statement, FCC Radio Frequency Exposure Limit 1.1310 Health Canada Safety Code 6 MW FBDA-800AB-50W-DIV Fiber Optic Repeater System The MW FBDA-800AB-50W-DIV Fiber Optic Repeater System has been tested and the performance characterized in accordance with the MPE requirements of FCC 47 CFR and RSS 102. At the maximum operating frequency of 894MHz the MPE limit for the General Population/Uncontrolled Exposure is 0.6mW/cm 2 (f/1500mW/cm 2 ). This device complies with this limit at the following line of sight distances from the antenna element: MW FBDA-800AB-50W-DIV : 51.5cm The analysis is provided below. Power Density (S) = EIRP/(4πR 2 ), Therefore, R≥√EIRP/S x 4π Using this calculation: Maximum Antenna Gain = 3dBi Maximum output power = 40dBm S = 0.6 mW/cm 2 EIRP = 43dBm or 20W(max. worst case) Theref ore, R= 51.5cm This minimum safe distance for the general population of 51.5cm shall be stated in the installation & operators instruction manual under the RF Safety Exposure Warning Statement.
