Why is the Laser LED Green and Status LED Red on my DKT Comega OFA-CCS Amplifier?
If the Laser LED is green and the Status LED is red, the optical output power of your DKT Comega Amplifier may not meet the specified output power. Check the Laser ON/OFF state on the Laser Control menu to resolve this issue.
What to do if Laser LED is Red and Status LED is Red on DKT Comega OFA-CCS?
If the Laser LED and Status LED are both red on your DKT Comega Amplifier, it indicates that the optical input power of the EDFA does not meet the minimum requirement. First, measure whether the optical input power from the optical source or transmitter satisfies the minimum optical input power condition. If it does, clean the surface of the optical input connector.
What to do if Laser LED changes from Green to Red and Status LED changes from Yellow to Red on DKT Comega OFA-CCS Amplifier?
If the Laser LED changes from Green to Red and the Status LED changes from Yellow to Red on your DKT Comega Amplifier, the internal temperature of the Pump Laser Diode of the EDFA is out of the specified range. It requires either adjustment or replacement.
How to fix Laser LED Green and Status LED Yellow on DKT Comega OFA-CCS Amplifier?
If the Laser LED is green and the Status LED is yellow on your DKT Comega Amplifier, the capability of the Pump Laser Diode may have degraded, or it could be out of order. The EDFA needs to be repaired or replaced.
