1. 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.

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

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.
2.2.1 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 each one of the 2 RX paths a separate 30 dB attenuator is connected at
the F/O unit output.

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.
