7320 IFL Installation and User's Guide

2. Introduction to the 7320 IFL

The Sat-Light 7320 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 7320 IFL
consists of an optical transmitter (7320T) which receives the L-Band signal from the LNB
and an optical receiver (7320R) which connects to a satellite receiver.
The 7320T and 7320R modules plug into a 7000M 3U chassis/power supply which enables
expansion of the system to accommodate any 6 Sat-Light modules. Accessories include the
Model 7000S Standby Power Supply, the Model 2000 1:1 Redundant Switch, the Model
2100 Amplifier, and the Model 7050-4 Serial Data Multiplexer, an asynchronous data link.
The 7320 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 7320 Links RF
circuitry, guarantees superior signal quality. The 7320 gives more than 25 dB carrier to noise
performance in a full multichannel environment.
Gain Control provides for optimization of the RF signal. LEDs, and back panel monitors and
alarms allow for complete system status monitoring and for interfacing with M & C systems.

2.1 Options

The 7320 IFL comes with a variety of options:
1. LNB powering - The transmitter unit can provide 15 VDC for optional LNB
powering.
2. 50 Input/Output Impedance/BNC RF connector. Standard impedance is
75 /F type, female connectors are standard.
3. Standalone unit - The 7320 IFL can be installed as a standalone unit. If the 7320
is used as a standalone, a separate power supply must be used.
On the side of the 7320T and the 7320R units is a sticker
Under each option is a square. If the unit includes a particular option the square under
the option should be marked. For example in Figure 1 the LNB option is marked.
