Attenuator
If your tunable laser has an built-in optical attenuator, move to
[Power Mode], press Enter, move to <Automatic>, 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
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:
1
Press [Details].
2
Move to [Optical Output] and press Enter.
3
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 Figure 77,
•
<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
•
<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.
