Model 3000
The Model 3000 L-Band Satellite Transport System
brings a state-of-the-art modular approach to the
demanding Teleport environment. The link transmits
in the frequency range of 950-2150 MHz and
employs a number of feature rich components to
create a highly reliable system. The system may be
ordered in a stand-alone or 3RU rack-mount
configuration. The laser type may be specified for
conventional 1310 nm or 1550 nm operation,
CWDM operation or DWDM operation. Both the
transmitter and the receiver may be specified for 75
Ohm or 50 Ohm inputs. The transmitter may also be
ordered to provide +18 Volts DC for LNB power. The
3RU rack chassis configuration offers increased
system reliability via dual, redundant power supplies
and hot-swappable modules. The system provides a
-20 dB RF test point and other test points to
determine laser current draw, laser cooler current
draw, and ground, further ensuring proper Teleport
system operations.

The modular transmitter design allows the
user to choose a variety of options for
impedance, packaging, wavelength, and
optical connector type.
Model 3000 optically transports the entire L-Band
frequency range (950-2150 MHz) and is designed
to operate in stringent teleport environments.
100 km+ depending on configuration.
User-selectable gain controls allow for
automatic, manual, and fixed gain
adjustments in the field.
3RU chassis mounted modules are
hot-swappable to ensure maximum
system up-time.
The Model 3000 is format independent
and provides a -20 dB RF test point for
ease of use, commissioning, and troubleshooting.
