When APC mode is selected the user must enter the target output power setting in units of dBm.
The actual maximum output power which is attainable will be based on the input power level and
the maximum Bias Current Limit for the specific amplifier. An example of APC mode is shown in
Figure 7.2.2-4, in this case the user has entered a target output power of +4.0 dBm.

The Loss of Signal (LOS) level can also be edited by the user and has a range from -45 dBm to
+10 dBm (for the standard configuration). To edit this value, click inside the box, make the
necessary edits, then press Enter to send the changes to the module. The LOS indicator on the GUI
will be a green color whenever the incoming optical signal is at a greater power level than the LOS
level. The indicator will be red whenever the incoming optical signal level is less than the LOS level
as shown in Figure 7.2.2-5.
