The LED beside the primary optical output is lit constantly, while the LED beside
the secondary optical output flashes. For example, if you select
<
Both (master:2)
> as the regulated path, the LED beside Output 2, the High
Power Output, is lit constantly and the LED beside Output 1, the Low SSE optical
output, flashes.
How to Set the Optical Output
1
Move to [
Output
] and press
Enter
.
2
Move to your chosen optical output and press
Enter
.
How to Enable the Optical Output

If you enable the laser output for a module with two optical outputs by pressing
the
Active
hardkey on the module’s front panel, you automatically choose the
optical output for that module. For example, if you press the
Active
hardkey
beside Output 1, the Low SSE optical output, you choose <
Low SSE
> as the
optical output, the LED beside the Output 1 lights constantly, and you see the
screen in Figure 66.
Furthermore, if you then proceed to press the A
CTIVE
hardkey beside Output 2,
the High Power Output, you choose <
Both
(master:1)
> as the optical output, the
LED beside the Output 2 flashes.
If you press the
Active
hardkey beside a flashing LED, you disable the
unregulated optical output. If you press the
Active
hardkey beside a constantly lit
LED, you disable both optical outputs.
How to Set Power and Attenuation
Attenuator
If your tunable laser has an built-in optical attenuator, you can set the laser
output power and then set the attenuation.
1 Move to the Tunable Laser channel and press [Details].
2 Choose the Output 2, the high power output, for a Tunable Laser module
with two optical outputs, as described in
“How to Set the Optical Output”
. For modules with one optical output this is not necessary.
3 Move to the power parameter, [P], and press [Pwr unit].
4 Move to <dBm> and press
Enter
.
5 Type 5.000, using the numerical keypad and press
Enter
.
