2. Introduction to the 7310D
The Sat-Light7310D broadband (10 - 2200 MHz) fiber optic link is designed for a
wide range of antenna remoting applications, wireless or satellite. The 7310D
operates over singlemode fiber covering distances of up to 15 kilometers away while
preserving excellent signal quality. The 7310D 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 7310DT and 7310DR modules plug into the 7180M1, 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 7310D is a broadband transmission link; all standard satellite modulation formats
can be transmitted (i.e. QPSK, FM, etc.). The 7310D 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 7310D Links RF
circuitry, guarantees superior signal quality. The 7310D is capable of more than 35
dB carrier to noise performance2in 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 7310D comes with a variety of options:
1. 75 Ω/F type or 50 ΩSMA 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 - 2200 MHz.
3. Standalone unit; the 7310D can be installed as a standalone unit. If the
7310D is used as a standalone, a separate power supply must be used.

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 loss5.
Alternatively, use a DVM to measure the voltage at:
•pins J13-P9 through J13-P16 for the slot being measured (Refer to Table
6on 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 38.
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.
5Fiber 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.
