Model 3079 Short Range IF 70/140
MHz Optical Transmitter is designed to work with the
Model 3080 Receiver to transport 50 Ohm signals in the
10 to 200 MHz range, specifically 70 or 140 MHz signals
for satellite uplink or downlink applications up to 2 km. The
link may be ordered in a stand-alone or 3RU rack-mount
configuration. The 3RU configuration rack-mounts up to
eight hot-swappable 3079 transmitters and/or 3080
receivers and two power supplies in a 3RU 19" rack
chassis for increased system reliability. The Model 3080
receiver provides the user with manual gain control which
allows the user to tailor the module input and output levels
to maintain consistent performance. Available with 1310
nm Fabry-Perot (FP) optics, the Model 3079 transmitter
can be configured to meet almost any short range design
need. Indicator LEDs for Laser Status, RF Level, and
Local/Remote Operation (Tx), as well as an indicator for No
Optical (or low optical) input (Rx) allow the user to quickly
assess the link’s operational status. The 3RU version may
be used with Force's SNMP compatible power supplies for
SNMP monitoring and control of the link. As part of the
3000 Series L-Band and IF family, the Model 3079
provides the professional satellite operator a high
performance solution for satellite communications.

Link gain can be adjusted to specified limits up to a maximum loss of 2 dB (2 km).
The Optical Loss knob controls the link gain over the full optical loss range.
Optimal ranges are: -15 to -35 dBm, small aperture and 0 to -20 dBm, large aperture.
SFDR = 2/3 (Input Third Order Intercept (dBm) - Equivalent Input Noise (dBm/Hz)).
Group delay specification is for 30-200 MHz.
