STATUS DISPLAY PANEL OPERATION
The microprocessor software monitors the function of a number of system parameters. Pressing the ▼and▲buttons allows
the LCD to display key working parameters sequentially.
Optical Input Power
Input power: INPUT = display input power (dBm)
 Input power = +10dBm = >alarm
 Input power = -10dBm => display NO INPUT =>shut down the power supply of the laser.
 Input power = 0dBm => reach fixed output power.
Optical Output Power
Output: OUTPUT = display output power (dBm)
 Tolerance = ±0.2dBm
 No input = power supply of the laser will be shut down automatically => display NO INPUT => NO OUTPUT
Laser Temperature
Laser temperature: TEMP = laser temp is set to operate in the range of 20-30°C
 if exceeded => LCD will display ” READY” => red LED indicator will light, and the power supply of the laser will shut down auto-
matically.
Laser Bias
Bias: BIAS = Bias is the key index of the laser, if it exceeds the fixed range power supply of the laser, the power supply will
be shut down automatically to protect the laser.
Laser Heating/Cooling
Cooling/heating: COOLING/HEATING = standard temperature for laser 25°C
TEC
Thermoelectric cooler 25°C
 At heat circumstance, LCD display => COOLING
 At cool circumstance, LCD display =>HEATING
Voltage
+5V Voltage: +5V READS… => ±0.5V alarm
-5V Voltage: -5V READS… => ±0.5V alarm
Serial Number
Displays the serial number of the EDFA.
IP Address for RS-232 Connector
The IP address code can be set by the operator via the RS-232 connector on the rear panel.
