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) One fiber, for both uplink and downlink directions 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. FO-50W SYS Page 3 of 12 Dekolink WIRELESS Ltd. 16 Bazel St. Qiryat-Arieh Petah-Tikva, Israel, 49510 Tel- 972-3-9180-180 Fax-972-3-9180-190 e-mail: marketing@dekolink.com web www.dekolink.com 1.2 FBDA The FBDA is installed near the area to be covered and is connected to the mobile antenna. 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 pre-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. Mobile ANT.

SUBSYSTEM DESCRIPTION: 2.1 FBDA Refer to installation and operation instructions for MW-FBDA-PCS-xxx-50W 2.2 FBIU The FBIU is the BTS interface of the system. It contains one Fiberoptic transceiver and attenuators for uplink and downlink paths and power supply. 2.2.1 Fiberoptic transceiver The Fiberoptic transceiver converts the signal form RF to optical in the downlink direction and from optical signal to RF in the uplink direction. 2.2.2 Attenuators Assuming that the output power of BTS is +30dBm, a 30 dB high power external attenuator is required. In practice, more attenuation can be added for different system setting. For the RX path a separate 30 dB attenuator is connected at the F/O unit output.
