The 7870 IFL is a 10 – 200 MHz IF fiber optic link used primarily in short distance, single channel video applications with high input/ output power levels. The 7870 IFL consists of an optical transmitter (7870T) which receives signals from satellite modems, video modulators, or exciters and transmits them to an optical receiver (7870R) via singlemode fiber.

The 7870T and 7870R modules plug into a 7180M, a 3U chassis and power supply, which enables expansion of the system to accommodate up to eight Sat-Light™ modules. Accessories include the Model 7001P Power Supply, the Model 2040 1:1 Redundant Switch, the Model 2100 Amplifier, and the Model 7050 Serial Optical Multiplexer, an asynchronous data transceiver.

The 7870 IFL transmits all satellite modulation schemes - digital or analog. Any FM modulated RF signal is transmitted accurately. The RF signal is directly modulated and adds virtually no phase noise to the original signal. The direct modulation, along with extremely flat amplitude and group delay, guarantees low bit error rate (BER) and high signal quality, independent of distance.

LEDs, and back panel monitors, and alarms allow for complete system status monitoring and for interfacing with monitor and control (M&C) systems. Gain Control at the Receiver sets the RF level.
