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. Page 3 of 3 FO-800AB-50W SYS.doc

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.

SUBSYSTEM DESCRIPTION: 2.1 FBDA Please refer to installation and operation instructions for FBDA-800AB-50W-DIV 2.2 FBIU The FBIU is the BTS interface of the system. It includes Fiberoptic transceiver, duplexer and attenuator for main uplink and downlink , uplink diversity Fiberoptic transmitter receiver and attenuator, and power supply. 2.2.1Fiberoptic 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 DUPLEXER The duplexer separates the uplink and downlink signals to anable one RF cable connection to the BTS. 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. In practice, more attenuation can be added Page 5 of 5 FO-800AB-50W SYS.doc
