- 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 upli
- 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
- or diversity applications the uplink path is duplicated using separate antenna, filter, pre-amplifier and Fiberoptic transmitter.

4.4 System assembly:
4.4.1 Connect BTS Tx to Tx antenna port on FBIU. (Another 10dB attenuator
can be connected to the RF IN port of the Fiberoptic transceiver in the FBIU
and the Rotary Attenuator on the FBIU front panel adjusted slightly for
system performance optimization).
4.4.2 Connect Spectrum analyzer or Power Meter through High Power
Attenuator of 40 dB to the Antenna port of the FBDA.
4.4.3 Turn the system ON, make sure that output power of BTS is no more
than +30dBm. In case of higher power, higher attenuation is needed
between BASE and FBIU.
4.4.4 Adjust Gain on the Fiberoptic transceiver front panel in the FBDA so
that RF power at the output is +40±1dBm.
4.4.5 Connect diversity RX port on FBIU to the diversity receiver in the BTS.
Connect RX port on FBIU to the Rx port in the BTS
4.4.6 Turn power off. Disconnect Spectrum analyzer and attenuator from
Antenna port on the FBDA and connect Mobile Antenna and Diversity to the
FBDA.
4.4.7 Turn power on.
