Figure 7.2.2-5 - LOS Indicator is Red When Optical Power Level is Less than LOS Level
Figure 7.2.2-6 illustrates the operational difference between having the Auto Shutdown Mode
enabled versus disabled. In this case, there is approximately -40.0 dBm input power present. The
left window shows the amplifier being disabled since the Auto Shutdown Mode is activated, the
output power level is displayed as the minimum possible value. The right window shows the
amplifier still enabled with an optical output power level of approxi9.3 dBm.

Versus Disabled
The Module Fault Status indication is shown in the GUI window as well as the LED located on the
top side of the module. The Module Fault Status is a logical OR of several alarms which are LOS,
laser bias current exceeds the maximum current limit, laser pump temperature out of valid
