7410F IFL Installation and Users Guide

2. Introduction to the 7410F IFL

The Sat-Light 7410F 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 7410F IFL consists of an optical transmitter (7410FT) which receives
the L-Band signal from the LNB and an optical receiver (7410FR) which connects
to a satellite receiver.
The 7410FT and 7410FR modules plug into the 7180M
supply, which enables expansion of the system to accommodate any
modules. Accessories include the Model 7001P Power Supply, the Model 2000
1:1 Redundant Switch, the Model 2100 Amplifier, the 2300 Relay Adaptor, and
the Model 7050 Serial Data Multiplexer, an asynchronous data link.
The 7410F 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 7410F Links RF circuitry, guarantees superior signal
quality. The 7410F gives more than 30 dB carrier to noise performance in a full
multichannel environment.
Automatic Gain Control (AGC) at the transmit site provides for optimized signal
levels over various input power levels. Manual Gain Control (MGC) at the
receive site provides compensation of any signal loss caused by the link. LEDs,
and back panel monitors and alarms allow for complete system status monitoring
and for interfacing with monitor and control (M&C) systems.

2.1 Options

The 7410F IFL comes with a variety of options:
1.
LNB powering; the transmitter unit can provide 14 VDC for optional
LNB powering.
50 Ω Input/Output Impedance/BNC or SMA RF connector; standard
2.
impedance is 75 Ω/F type, female connectors.
3.
Standalone unit; the 7410F IFL can be installed as a standalone unit. If
the 7410F is used as a standalone, a separate power supply must be
used.
