1.5.1. Personal Safety
WARNING
OPTICAL RADIATION
APPLYING POWER TO THE TRANSMITTER UNIT WILL
CREATE A LASER ENERGY SOURCE OPERATING IN CLASS I
AS DEFINED BY IEC 825-1. USE EITHER AN INFRARED
VIEWER, OPTICAL POWER METER OR FLUORESCENT
SCREEN FOR OPTICAL OUTPUT VERIFICATION.
AC POWER HAZARD
THE RACKMOUNT POWER SUPPLY LINE IS EMI FILTERED.
THE CHASSIS IS CONNECTED TO EARTH GROUND IN
COMPLIANCE WITH SAFETY REQUIREMENTS. ALWAYS USE
THE 3 PRONG AC PLUG WITH EARTH GROUND TO AVOID
POSSIBILITY OF ELECTRICAL SHOCK HAZARD TO
PERSONNEL.
1.5.2. Equipment Safety
1. Fuses: The 7180M does not have fuses. If the unit fails, pull the
power supply out from the chassis and then push it back in.
2. The input of the transmitter has an optional built-in bias for
inserting DC power up the coax to the LNB. Make certain any
equipment or test equipment connected to the transmitter input can
withstand this bias.
3. The output of the receiver is AC coupled and can withstand the bias
from a satellite receiver. Do not exceed 25V DC bias.
4. Do not allow any dirt or foreign material to get into the optical
connector bulkheads. This may cause damage to the polished optical
connector end faces.
5. The optical fiber jumper cable bend radius is 3 cm. Smaller radii
can cause excessive optical loss and/or fiber breakage.
6. If multiple transmitters are installed in the chassis allow sufficient
room for adequate ventilation; otherwise the units may overheat
causing possible safety hazard or equipment damage.
7. When several units are installed on one 7180M chassis, ensure that
the total current consumption (including any LNB bias) does not
exceed 6A per chassis.

2. Introduction to the 7410F IFL
The Sat-Light7410F IFL transmits an L-Band RF signal over singlemode fiber
from a satellite antenna LNB to control room equipment up to two kilometers
away. The 7410F IFL consists of an optical transmitter (7410FT) which receives
the L-Band signal from the LNB and an optical receiver (7410FR) which connects
to a satellite receiver.
The 7410FT and 7410FR modules plug into the 7180M1, a 3U chassis/power
supply, which enables expansion of the system to accommodate any 8Sat-Light
modules. Accessories include the Model 7001P Power Supply, the Model 2000
1:1 Redundant Switch, the Model 2100 Amplifier, the 2300 Relay Adaptor, and
the Model 7050 Serial Data Multiplexer, an asynchronous data link.
The 7410F IFL is a broadband transmission link; all standard satellite modulation
formulas can be transmitted (i.e. QPSK, FM, etc.). The RF signal is directly
modulated and adds virtually no phase noise to the original signal. The direct
modulation, coupled with the 7410F Links RF circuitry, guarantees superior signal
quality. The 7410F gives more than 30 dB carrier to noise performance in a full
multichannel environment.
Automatic Gain Control (AGC) at the transmit site provides for optimized signal
levels over various input power levels. Manual Gain Control (MGC) at the
receive site provides compensation of any signal loss caused by the link. LEDs,
and back panel monitors and alarms allow for complete system status monitoring
and for interfacing with monitor and control (M&C) systems.
2.1 Options
The 7410F IFL comes with a variety of options:
1. LNB powering; the transmitter unit can provide 14 VDC for optional
LNB powering.
2. 50 ΩInput/Output Impedance/BNC or SMA RF connector; standard
impedance is 75 Ω/F type, female connectors.
3. Standalone unit; the 7410F IFL can be installed as a standalone unit. If
the 7410F is used as a standalone, a separate power supply must be
used.

2.4 Block Diagrams
Figure 4 - 7410FT Transmitter Block Diagram
The 7410FT Transmitter accepts RF input signal levels ranging from
-40 to -20 dBm total power (i.e. at 10 channel loading this is equivalent to
-50 to -30 dBm per channel). The unit amplifies the signal, and feeds it to a
laser diode which linearly converts the broadband RF signal to light
intensity.
Figure 5 - 7410FR Receiver Block Diagram
The 7410FR Receiver receives the optical intensity signal, and linearly
converts the signal back to RF. The Receiver then amplifies and reproduces
the L-Band RF signal.

3.3 Setting Up the Receiver
1. Place the 7410FR Receiver in the 7180M Chassis, unless a 2000 RF
Switch is installed (refer to Figure 7, page 21). The operating base plate
temperature must be between -10°C to 55°C.
Note
If a 2000 RF Switch(s) is being installed, then slots 2 and/or 5 of the 7180M
are reserved for the switch(es).
2. Apply AC power to the chassis. The Power Supply’s LED should be lit.
3. Using an optical power meter, measure the optical power coming to the
Receiver from the fiberoptic cable. The power levels of the Receiver should
be the power level measured at the Transmitter minus the fiber loss4.
Alternatively, use a DVM to measure the voltage at:
•pins J13-P9 through J13-P16 for the slot being measured (Refer to
Table 6 page 34 for details regarding J13 pinouts) (7180M
Rackmount). The voltage level should be 1V for each 1 mW measured
at the Receiver input.
•at pin #5 of the 9 pin connector (standalone)
4. On the rear panel connect the fiberoptic cable to the Optical Connector.
The Opt. and RF LEDs should be lit.
5. On the rear panel, connect the coax cable to the RF Output Connector.
6. Adjust the Gain Control Potentiometer to give the desired output power.
Using a small screw driver, turn the potentiometer (located on the front
panel) to increase or decrease the gain.
Note
If either LED is not lit, refer to Troubleshooting on page 36.
Note
The potentiometer is 10 turns potentiometer.
•To increase the gain, turn the potentiometer clockwise.
•To decrease the gain, turn the potentiometer counterclockwise.
For more information refer to Aligning the Fiberoptic Link on page 24.
4Fiber loss is defined as:
(0.4 dB/km x length (km) of the fiberoptic cable) + (0.5 dB x number of connectors).
For example if a link was 10 kilometers long and had two connectors the loss would be:
(0.4 dB/km x 10 km) + (0.5 dB x 2) = 5.0 dB.
