HOOTS Optical Talk Set

fiber
to transmit
fiber
You will need a pair of fibers terminated into a
connector at both ends of the link in order to use the
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
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.

D = 20 dB / (1.5 dB/km) = 13.33 km
To calculate the talkset’s maximum communication distance:
D = R / A
where: D = talkset distance
R = dynamic range (HOOTS = 20 dB)
A= typical fiber attenuation at specified
8
Example (
8
= 1300nm, R = 20 dB, A = 1.5 dB/km):
Note: the fibers used for communication may be different
than the example above. Consult the fibers data sheet for
its attenuation parameter.
