The minimum power level displayed for both the input and output monitors is equal to the lowest
value of the respective ranges which is -45 dBm for the input and -35 dBm for the output in the
standard configuration. Therefore, if the output is disabled, the output power monitor will display
-35 dBm. Since the standard module configuration includes a single stage isolator at the input, it is
possible to have backward ASE power seen at the input connector if there is no input optical
power. So in this case, the input power level would never go all the way down to -45 dBm due to
the backward ASE power. If this is not desired please contact TPC and we can install a dual stage
isolator to prevent this condition, however, the module’s noise figure will increase due to the
additional isolation.
A temperature sensor is mounted on the PCB and its value in degrees Celsius is continuously
updated on the display.

The user can manually Enable or Disable the amplifier output with the dropdown menu at the top-
right of this window. Similarly, Auto Shutdown Mode can be Disabled or Enabled and this controls
the module’s operation when an LOS alarm occurs. If Auto Shutdown Mode is Enabled, the
amplifier output is disabled whenever an LOS alarm is active as shown in Figure 7.2.2-2.
