2. Introduction to the 7310D
The Sat-Light
7310D 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 7180M
1
, 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 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 7310D 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 - 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.
