1.
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.
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 45 dB RF GAIN in both directions.
Both optical signals for Uplink and Downlink are carried on two fibers or a single fiber
using WDM.
The Rfiber+ RF output power must be aligned to 0 dBm for proper operation.
The downlink path uses a 50 Watt power amplifier with AGC control. The AGC control
is located on the power connection unit.
Downlink gain can be adjusted using a step attenuator for required output power.
The uplink uses a low power AGC amplifier to drive the uplink F/O transmitter. The
AGC is set to 0 dBm, which is the optimum power permitted by the F/O transmitter.
Uplink gain can be adjusted by 16 dB continuous trim potentiometer on the uplink
amplifier.

2. COMPONENTS DESCRIPTION:
2.1 DUPLEXER
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.
2.2 UPLINK PRE-AMPLIFIER
The uplink pre-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 attached to this amplifier turns on TEMP alarm when the
temperature exceeds 80° C. This amplifier has AGC circuitry that can be turned on to
limit transmitted power. The AGC switch is located on the power connection unit.
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 0.08-2 GHz frequency range.

The RFiber+TM main features are:
1.
Protocol transparency; i.e. any standard can be faithfully transmitted.
2.
An optional serial port (RS232) is installed into each unit. This port allows
data communication over the same fiberoptic cable.
3.
Max. input RF power for normal operation – 0dBm.
4.
Manual Gain Control is standard in receiver to compensate for optical loss
across the fiber.
The following drawings show sample front and rear panels of the RFiber+TM unit
Fig. 2 : - RFiber+TM Front Panel
Fig. 3 : - RFiber+TM Rear Panel
On the Front Panel of the RFiber+TM unit (Fig 2.) are three LEDs. The LEDs should be
on when the unit is in use. The following table describes the LEDs.

Indicates when the power is on.
The “Gain” trimmer on the front panel is used to adjust signal level at the RF out of the
Rfiber+, especialy for optical loss compensation of the optical fiber.
2.5 MONITOR UNIT
The FBDA monitor performs the following functions:
a) Monitors the DC supply voltage of the FBDA. The fault LED illuminates when the
voltage is beyond the specified limits.
b) Monitors the current to each active element and the internal fan. 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) Monitors the Thermostat for high temperature alarm.
e) Provides automatic alarm function. Whenever any fault occurs or when the power
supply voltage is under it’s limit, the unit sends summarized alarm signal to the base
station via the Fiberoptic transmitter data port.
e) Provides self test for the alarm functions. The pushbutton switch on the Monitor
unit turns on all the alarm LEDs and initiates the summarized alarm.

4. RF EXPOSURE WARNING
In order to satisfy the FCC RF exposure requirements, you must ensure that the
installation complies with the following:
The antenna is connected via cable that has typical 1~10 dB attenuation (depends on
the length of the cable) to the FBDA MOBILE port.
There are two applications: Outdoor and Indoor.
In the case of Outdoor the type of antenna is omnidirectional (isotropic) with 0 to 2 dBi
typical gain, or wide beam with up to 3 dBi gain, and is installed on a mast to cover
shadowed, outdoor, area. This antenna must be installed to provide a minimum
separation distance of 1 m (100 cm) from persons within the area
In the case of Indoor coverage the power is split to several, omnidirectional (isotropic)
antenna with 0 to 2 dBi typical gain, and distributes to different indoor areas (in
building floors, tunnels, basements, parking lots, shopping centers etc.). Typical
specifications: gain: 2 dBi, VSWR: better than 2:1 , Impedance: 50 ohm. At least 5
such antenna must be connected to the BDA using cables and splitters. In this case
the max. EIRP from each antenna will not exceed 3W so that the minimum required
separation distance from persons within the area is 20cm.
Less separation is needed if the power is divided into more than 5 antenna covering
many floors or areas.
