W:
Attenuator
If your tunable laser has an built-in optical attenuator, move to
[
Power Mode
], press
Enter
, move to <

>, and press
Enter
.
1
Move to the power parameter, [
P
]
,
and press [Pwr unit].
2
Move to <W> and press
Enter
.
3
Press
Enter
to start editing the output power value.
4
Enter 555.000, press [Unit+] or [Unit

], as required, to select
µ
W as the power
units, and press
Enter

How to Set the Optical Output
To set the Optical Output of a Tunable Laser module with two optical outputs:

Use the Modify Knob to move to one of the following:
–
<
High Power (2)
>, a high power optical output, for example, for use in
tesing Erbium Doped Fiber Amplifiers (EDFAs), you see a screen similar to
–
<
Low SSE (1)
>, a lower power optical output with low Source Spontaneous
Emission (SSE), for example, for use in passive component test, you see a
screen similar to Figure 66,
–
<
Both (master:2)
>, where both optical outputs can be enabled but only the
output of the high power optical output can be regulated, and
–
<
Both (master:1)
>, where both optical outputs can be enabled but only the
output of the low SSE optical output can be regulated.
