Important Information
Reporting Defects
The units were inspected before shipment and found to be free of
mechanical and electrical defects.
Examine the units for any damage which may have been caused in
transit. If damage is discovered, file a claim with the freight carrier
immediately. Notify Foxcom as soon as possible.
Note Keep all packing material until you have completed the
inspection.
Precautions
Personal Safety
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.
Equipment Safety
To avoid damaging your product, please observe the following:
1. The output of the receiver is AC coupled and can withstand the
bias from a satellite receiver. Do not exceed 25V DC bias.
2. The input of the transmitter has an optional built-in bias for
inserting DC power up the coax to the LNB. Make certain that
any equipment or test equipment connected to the transmitter
input can withstand this bias.
3. 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.
4. The optical fiber jumper cable bend radius is 3 cm. Smaller radii
can cause excessive optical loss and/or fiber breakage.
5. 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.
6. Fuses: The 7180M chassis does not have fuses. If the unit fails, pull
the power supply out from the chassis and then push it back in.
7. When several units are installed on one 7180M chassis, ensure
that the total units’ current consumption (including any LNB
bias) does not exceed 6A.

The 7870 IFL is a 10 – 200 MHz IF fiber optic link used primarily in
short distance, single channel video applications with high input/
output power levels. The 7870 IFL consists of an optical transmitter
(7870T) which receives signals from satellite modems, video
modulators, or exciters and transmits them to an optical receiver
(7870R) via singlemode fiber.
The 7870T and 7870R modules plug into a 7180M, a 3U chassis and
power supply, which enables expansion of the system to
accommodate up to eight Sat-Light™ modules. Accessories include
the Model 7001P Power Supply, the Model 2040 1:1 Redundant
Switch, the Model 2100 Amplifier, and the Model 7050 Serial Optical
Multiplexer, an asynchronous data transceiver.
The 7870 IFL transmits all satellite modulation schemes - digital or
analog. Any FM modulated RF signal is transmitted accurately. The
RF signal is directly modulated and adds virtually no phase noise to
the original signal. The direct modulation, along with extremely flat
amplitude and group delay, guarantees low bit error rate (BER) and
high signal quality, independent of distance.
LEDs, and back panel monitors, and alarms allow for complete
system status monitoring and for interfacing with monitor and
control (M&C) systems. Gain Control at the Receiver sets the RF
level.

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 fiber optic cable. The power levels of the
Receiver should be the power level measured at the Transmitter
minus the fiber loss2.
Alternatively, use a DVM to measure the voltage at:
• pins J13-P9 through J13-P16 for the slot being measured (See
pinouts) (7180M Rackmount). The voltage level should be 1 V
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 coax cable to the RF Output
Connector.
5. 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.
Notes
1. The potentiometer is 10 turn potentiometer.
• To increase the gain, turn the gain control clockwise.
• To decrease the gain, turn the gain control counterclockwise.
2. Fiber loss is defined as:
(attenuation/km x length (km) of the fiber optic cable) + (0.5 dB ×
number of connectors).
For example if a signal with an optical wavelength of 1310 nm is
transmitted over a link 10 kilometers long which had two connectors
the loss would be:
(0.4 dB/km × 10 km) + (0.5 dB × 2) = 5.0 dB

Powering the IFL
• Transmitter power requirement: +14 VDC @ 200 mA
• Receiver power requirement: +14 VDC @ 250 mA.
• The Standalone Transmitter/Receiver is powered by a Foxcom
supplied external DC power supply.
• The Rackmount Transmitters/Receivers are plugged into the
rackmount chassis. The chassis can accept and power up to eight
units.
Note At temperatures below10°C, the Transmitter’s internal heater
will require an additional 100 mA. The Transmitter’s total
power requirement will then be 300 mA.
Caution Ensure that there is a good airflow around the chassis
rackmount.

7180M Chassis
The 7180M Chassis provides power to the plug in units. The power supply is a switching type. Each plug-in
regulates its own voltage. The power supply provides:
• 14 VDC stable
• AC input; 100 - 240 VAC
• Units can be plugged in “hot standby”

2.5 Connecting the Back Panel Jumpers
2.5
Connecting the Back Panel Jumpers
On the rear panel of the 7180M Back Panel are product selectors (JP1 to JP4). The 3 pin selectors (male) are the
connecting point between the slots and the back panel. One pin is for the transmitter/receiver (Tx/Rx), one is for the
optional 2040 1:1 Redundant Switch, and one is for the 7180M. A 2 pin jumper (female) is placed on the relevant pins to
complete the connection between the 7180M and the units. For example, if a 2040 Switch is being used, the jumper is
placed on the Switch-7180M pins.
To connect the jumpers:
1. Each jumper has two sets of pins, upper and lower. The upper pins are labeled SW (Switch) and the lower pins Tx/Rx.
2. If the 7180M has Tx or Rx units only, place all jumpers on the lower two pins.
Figure 8 Jumper Installation: Tx and Rx only
3. If the 2040 Switch is installed in Slot 2, place the JP1 and JP2 jumpers on the higher two pins and the JP3 and JP4
jumpers on the lower two pins.

The final step in installing the 7870 Interfacility Link is
re-adjusting the Receiver Gain Control for unity gain.
To set the unity gain (standard version)
1. Set the Signal Generator to -15 dBm. Alternatively measure the
operational input level.
3. Adjust the Receiver Gain Control for -15 dBm reading on the
power meter.

Troubleshooting
The 7870D Interfacility Link unit was tested before it left the factory.
However if you are experiencing difficulties see the list below for
possible solutions. if you are still experiencing problems, attempt to
isolate and identify the malfunctioning unit before consulting
Foxcom’s technical support.
Table 8 Troubleshooting the Transmitter
Problem
Possible Cause
1. Laser LED not on
a. No DC power to the unit. Possible
power supply problem or AC power
input problem. Check the power
supply fuse.
b.Verify LSRI monitor is between -4.2
and -4.8VDC. If not, laser may have
overheated. Disconnect power or
remove plug and allow to cool. Try
again with better airflow.
c. If an optical power meter is avail-
able, measure the optical power out
of the transmitter. The power
should between 0.5 mW[-3 dBm]. If
an optical power meter is not avail-
able, use another receiver to deter-
mine if there is optical power
emerging from the transmitter (use
a 5 meter jumper cable). If there is
no optical power, then the transmit-
ter unit is malfunctioning.
If any or all the above are not within
the guidelines, the transmitter unit is
faulty.

Appendix 1 Cleaning Fiber Optic Connections
Appendix 1.2.2 Compressed Air Method ......................................................................... 29
The unit has an FC/APC angle polished optical connector for very high optical return loss
performance. The units are specified into single mode fiber i.e. 9/125 micron core diameter.
Full performance is specified only for low return loss optical plant - meaning that the fiber
must be fusion spliced and all connections or splices must have a return loss greater than -60
dB. With these guidelines in mind, link lengths beyond 20 kilometers (DFB based products)
can be achieved with high performance. Specific performance and/or design assistance is
available by request from Foxcom.
If there is low/no signal or noisy signal at a Foxcom module, the connector should be cleaned.
Dirt on the inside connector tip can impair the flow of light causing problems in signal
transmission. Foxcom modules are sealed but dirt can occasionally enter during installation
and alignment.
The input and output optical ports of all Foxcom equipment are known in the fiber optic
world as bulkhead ports. Foxcom uses
FC/APC connectors.
The following materials are representative of the types of cleaning materials that should be
used for cleaning the fiber optic ports and connectors. They are available from several
suppliers.
