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 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.
Front Chapter
1.5.2 Equipment Safety
To avoid damaging your product, please observe the following:
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 output of the receiver is AC coupled and can withstand the bias
from a satellite receiver.
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. 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.
Do not exceed 25V DC bias.

Introduction to the 7310 IFL
2. Introduction to the 7310 IFL
The Sat Light™ 7310 broadband (10 - 2200 MHz) fiber optic link is designed for a
wide range of antenna remoting applications, wireless or satellite. The 7310
operates over singlemode fiber covering distances of up to 2 kilometers away
while preserving excellent signal quality. The 7310 consists of an optical
transmitter (7310T) which receives the RF signal and an optical receiver (7310R)
which connects to a demodulator or satellite receiver.
The 7310T and 7310R modules plug into the 7180M, a 3U chassis/power supply
that enables expansion of the system to accommodate any eight Sat-Light
modules. Accessories include the Model 7001P Standby Power Supply, the Model
2000 1:1 Redundant Switch, the Model 2100 Amplifier, and the Model 7050 Serial
Data Multiplexer, an asynchronous data link.
The 7310 is a broadband transmission link; all standard satellite modulation
formats can be transmitted (i.e. QPSK, FM, etc.). The 7310 can be used in a wide
variety of applications: cellular, PCS, MMDS, GPS, VSAT, CATV, Earth
Stations, Broadcast, Radar, and others. The RF signal is directly modulated and
adds virtually no phase noise to the original signal. The direct modulation,
coupled with the 7310 Links RF circuitry, guarantees superior signal quality. The
7310 is capable of more than 35 dB carrier to noise performance in a full band or
single carrier environment.
At the receiver site MGC maintains the RF level regardless of optical power or
distance from the transmission site. Front panel LEDs and back panel monitors
and alarms allow for complete system status monitoring and for interfacing with
M & C systems.
2.1 Options
The 7310 IFL comes with a variety of options:
1. 75 Ω/F type or 50 Ω SMA RF connector; standard impedance is 50 Ω
Input-Output Impedance/BNC, female connectors are standard.
2. Extended frequency - 10 to 2500 MHz; the standard bandwidth is
10 - 2150 MHz.
3. Standalone unit; the 7310 IFL can be installed as a standalone unit. If
the 7310 is used as a standalone, a separate power supply must be used.

3.1 Setting Up the Transmitter
1. Place the 7310T Transmitter in 7180M Chassis. The operating base plate
temperature must be between -10° C to +55° C.
2. Apply AC power to the chassis. The Laser LED should be lit.
3. Using an optical power meter, measure the optical power. Insert the
meter’s cable into the Transmitter’s optical connector. Power levels should
be between 0.4 - 1.0 mW.
Alternatively, use a DVM to measure the voltage at:
• pins J13-P17 through J13-P24 for the slot being measured (Refer to
Table 6 on page 35 for details regarding J13 pinouts) (7100M
Rackmount)
• at pin #6 of the 9 pin connector (standalone)
The power level should be -4.5 ± 0.3 VDC.
4. On the rear panel, connect the coax cable to the RF Input Connector. The
RF LED should be lit.
Installation
5. On the rear panel, connect the fiberoptic cable to the Optical 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.

3.3 Setting Up the Receiver
1. Place the 7310R Receiver in the 7180M Chassis, unless a 2000 RF
Switch is installed (refer to Figure 7, page 22). 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 loss

• pins
J13-P9 through J13-P16 for the slot being measured (Refer to
Table 6 on page 35 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 Trouble Shooting on page 37.
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 Cable on page 25.

Fiber 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.

• Transmitter power requirement: +15VDC @ 200 mA
• Receiver power requirement: +15VDC @ 270 mA
• The Standalone Transmitter/Receiver can be powered by a
Foxcom-supplied external DC power supply.
• The Rackmount Transmitters/Receivers are plugged into the 7100M
rackmount chassis. The chassis can accept and power up to six units.

3.5 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 2000 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 2000 Switch is being used, the jumper is placed on the
Switch-7180M pins.
To connect the jumpers:
