Model 3000
Long Range L-Band Transport
100 km+ depending on configuration.
Model 3000 optically transports the entire L-Band
frequency range (950-2150 MHz) and is designed
to operate in stringent teleport environments.
The modular transmitter design allows the
user to choose a variety of options for
impedance, packaging, wavelength, and
optical connector type.
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.
3RU and Stand-alone Modules
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.

NOTES ON ORDERING:
1. FC/APC connectors are also available. Replace SP in the part number with AP.
2. The “ZZ” in the part number specifies one of eight CWDM wavelengths or one of 32 DWDM ITU
channels. Contact a Force, Inc. Applications Engineer for complete part numbers. CWDM
wavelengths are 1471 nm, 1491 nm, 1510 nm, 1531 nm, 1551 nm, 1571 nm, 1591 nm, and 1611
nm, depending on the channel plan ordered. DWDM ITU channels are: Ch. 22-25 (4-ch. plan), Ch.
22-29 (8-ch. plan), Ch. 22-37 (16-ch. plan), and Ch. 21-36 plus Ch. 41-56 (32-ch. plan). See
