Warning
Exposure to class 1M laser radiation is possible. Access should be restricted to trained
personnel only. Do not view exposed fiber or connector ends when handling optical
equipment.
 Ensure adequate cooling and ventilation as specified.
 The installation and operation manual should be read and understood before units are put into
use.
 Always replace protective caps on optical connectors when not in use.
 The typical connectors fitted are SC/APC 8°. Note: 8° angle polished connectors must be used.
Cleaning
Use only a damp cloth for cleaning the front panel. Use a soft dry cloth to clean the top of the
unit.

Product User Manual (Optional)
Keep all AT51-F3ST packing boxes and packaging for future transport.
Use only the original AT51-F3ST packaging when transporting. This packaging has been
specifically designed to protect the equipment.
The AT51-F3ST requires a mains input of 90 VAC to 265 VAC at 50 to 60 Hz. The unit will
automatically adjust the power conversion for inputs within these ranges, with no switch
setting or other user intervention. Power consumption of the unit is 50 W maximum.
The transmitter is designed to operate with an ambient temperature of -5 °C to +65 °C with
humidity up to 95 %. Free ambient air should be maintained around all sides of the unit. Care
should be taken to ensure that the air flow around the unit is unrestricted.
The AT51-F3ST should have a minimum ventilation clearance of 1 RU above and below the
transmitter.
Warning
DO NOT expose AT51-F3ST to conditions which would permit condensation to form on
the inside of the transmitter.
DO NOT operate AT51-F3ST outdoors.

Warning
Exposure to class 1M laser radiation is possible. Access should be restricted to trained
personnel only. Do not view exposed fiber or connector ends when handling optical
equipment.
The following steps explain how the AT51-F3ST is to be installed.
1. Unpack the transmitter and inspect the unit as stated in Section 3.1.
2. Locate the transmitter in a 19” cabinet ensuring adequate ventilation and space for accessing the
rear ports and front-panel keypad.
3. Before connecting AC power to the unit, make sure that the LASER ON/OFF key is switched OFF
(front panel).
4. Use the supplied power cord to apply mains power to the transmitter.
5. Switch the AC power ON (switch located on the rear panel).
The ALARM LED will light red.
The LCD will light and display “Model: AT51-F3ST” and “KEY OFF” on start up.
6. Switch on the laser using the key switch.
Front panel shows "KEY ON…", Laser status LCD turns green from red, the unit enters self-
checking, after checking it enters working status, display " Descriptor"
Note
Allow 15 minutes for the transmitter to reach its stable operating temperature. Do
not connect the optical ports to the network or start aligning your system until
then.
7. Before connecting an RF signal, check that the power input level is within the acceptable range.
Refer to Section 2 for details.
8. Connect a matrix generator or head-end RF signal.
Note
The default control mode is AGC. The modulation control mode displayed in the
main menu is RF Mode = AGC.
9. Connect a fiber patch-cord from optical port to an optical power meter and verify the LCD reading
matches your power meter reading.
When the ALARM LED shows green, the transmitter is ready for full operation.
