Using the OLA as a Laser Source
You can use the OLA to launch laser light into any optical fiber or
device.
Using the Internal Laser
Depending on how the OLA was ordered, the instrument will
comprise one or two built-in Fabry-Perot lasers, that deliver linear
polarized laser light at the optical output with a power of about
-7.5 dBm.
The wavelength is either 1310 nm or 1550 nm. If the OLA is
equipped with both lasers, you can switch between these two
options.
How to Activate the Internal Laser
Pressing S
OURCE
O
N
/O
FF
will turn the internal laser on or off
respectively. As long as the internal laser is on, the source indicator
lamp at the front panel will be lit.
How to Switch the Wavelength
If there are two lasers installed, each of the OLA applications
provides a softkey to switch from 1310 nm to 1550 nm or vice
versa.
If you are not using any application, press I

and choose
“Source”. The current wavelength will be displayed. To change the
wavelength press
1550
or
1310
respectively.
