OWL LH-1310 - Laser High Output Optical Talk Set

General Features:

1. LED Transmitter Connector - this port houses a light-emitting diode that emits a continuous beam of 1310nm or 1550nm infrared light, depending upon configuration, that is designed to couple into singlemode fiber.
2. Power/Headset Stereo Jack - this stereo jack serves a dual purpose as both the power switch and the headset stereo jack.
3. Receiver Connector - this port houses a photodiode that receives optical signals from the transmitter on the opposite end of the fiber for conversion to voice.
4. Receiver Indicator LED - this LED indicates the presence of optical pulses used for voice communications.
5. Transmitter Indicator LED - this LED indicates the ON/OFF status of the talk set.

Operation

You will need a pair of fibers terminated into a connector at both ends of the link in order to use the Laser HOOTS. Connect to the transmit and receive fibers to the talk set connectors (as shown in the figure at right).
 
The other end must have its fibers connected opposite to the other, i.e. the transmit fiber on one end is the receive fiber on the other.
 
Connect the headset plug to the headset adapter, then plug the headset adapter into the headset jack on the Laser HOOTS.
 
If the fibers are connected correctly, then both the Transmit and Receiver LEDs will light, and communications can begin.
 
If the LEDs are not lit, double-check to make sure that the transmit and receive fibers are correctly positioned.

To calculate the talkset’s maximum communication distance:

D = R / A
where:
D = talkset distance
R = dynamic range (Laser HOOTS = 20 dB)
A= typical fiber attenuation at specified


Example (8 = 1300nm, R = 20 dB, A = 1.5 dB/km): D = 20 dB / (1.5 dB/km) = 13.33 km

Note: the fibers used for communication may be different than the example above. Consult the fibers data sheet for its attenuation parameter.

Maintenance and Calibration Procedures

• Repair. Repair of this unit by unauthorized personnel is prohibited, and will void any warranty associated with the unit.
• Battery Replacement. The battery compartment is covered by a sliding plate on the back of the unit. One 9v battery is required for operation.
• Cleaning. For accurate readings, the optical connectors on the HOOTS and the connectors on the patch cords should be cleaned prior to attaching them to one another. Minimize dust and dirt buildup by replacing the dust caps after each use.
• Warranty. The HOOTS comes standard with a two-year factory warranty, which covers manufacturer defects and workmanship only.
