LED Display and Alarms
The OT-1000-HH has three LED’s displaying Module, RF and P
OPT
status.
The table below shows an overview about what conditions trigger the LED’s on the front panel. The STATUS
LED summarizes the condition of the transmitter. The RF and P
OPT
LED’s give detailed information of the
input and output status of the transmitter.
Standard Operation LED Green
Non urgent alarm (warning) LED Yellow
STATUS LED
Urgent alarm LED Red
Nominal RF input power LED Green
RF input power out of nominal operation LED Yellow
Input RF LED
Loss of RF input power LED Red
Nominal optical output power LED Green
Lack of optical output power LED Yellow
Loss of optical output power LED Red
Output POPT LED
Standby – operation LED dark (switched off)
During a reset (after switching on) all LED’s will be Yellow. After few seconds, all LED’s will light green in-
dicating normal operation.
In case of warnings (non-urgent alarms) and alarms (urgent alarms) the LED’s indicate Yellow or Red. The
warnings and alarms are described in the following.
STATUS LED States
Normal operation: STATUS LED Green
Non-urgent alarms: STATUS LED Yellow
• Laser aging: Laser bias current is >115% due to degradation (aging). Laser may need to be replaced.
• Laser temperature: Laser Peltier cooler current is >70 % of limit or laser temperature deviation more than
2°C. Improve ventilation in order to decrease the operating temperature.
• Module temperature: Module temperature is out of +5 to +70°C operating temperature range.
• SBS pilot level failure Internal network management failure
Urgent alarms: STATUS LED Red
• Laser aging: Laser bias current is >120% due to degradation (aging). Laser may need to be replaced.
• Laser temperature: Laser Peltier cooler current at limit or laser temperature deviation more than 3°C.
Improve thermal heat flow in order to decrease the operating temperature.
• Module temperature: Module temperature is out of +5 to 70°C operating temperature range.
• SBS pilot failure
• Internal network management failure
In case of an urgent alarm, the transmitter should be switched off.
