LED COLOR EXPLANATION
Predicts the deflected circuit fault or laser aging. The
RED
transmitter needs repair.

RED
transmitter needs repair.
Laser temperature is hovering from 25 °C. Check whether
RED
the room temperature is still in the recommended range.
Continue to monitor the situation.
The laser output power has moved from the correct value
RED
but the circuit is locked. Continue to monitor the situation.
Laser temperature control loop fault. Check the room
RED
temperature and confirm whether it is still in the recom-
mended range. Continue to monitor the situation.
Optical transmitter environment temperature has moved
RED
from 25 °C. Monitor the situation closely until the warning
light has disappeared.
Optical transmitter environment temperature has
RED
moved from 25 °C. Monitor the status until the warning
disappears.
Modulator defl ection point is close to maximum. Continue
RED
monitoring. The defl ection may need to be reset.
Modulator deflection point is close to the maximum.
RED
Continue monitoring. The defl ection may need to be reset.
Transmitter inner environment temperature is close to

POSSIBLE RESOLUTIONS

I. Some of the warnings stated above can be resolved by restarting the power supply or pressing the "On/Off' button on the front
panel. Please notify your Taikan representative if the warning indicator is still on.
II. To prevent any type of warning please follow these setup requirements:
> Ensure that the transmitter is placed in a temperature controlled environment of 0 °C ~ 50° C, that is also dust free.
> Make sure the transmitter is properly ventilated and allow ample space for the rear fan to work
> Check the power supply to confi rm that it meets standard requirements. In addition check all connections are secure.
> Double check the changing of the RF gain.
> Keep the fi ber connector clean.
III. The modulator defl ector voltage warning can be resolved by resetting its defl ection. To reset the defl ection, press the "On/Off"
button and press it again to turn it on. It will take approximately 45 minutes for the transmitter to return to stable status. During this
period, the CSO value will be compromised, and the output and fl oating signal will decrease. This step should be carried out at a
time that would least affect your subscribers. Please contact your Taikan representative if this still does not resolve the situation.
LED COLOR EXPLANATION
Transmitter inner panel temperature is close to limita-
RED
tion. Check the surrounding temperature and continue to
monitor the device.
RF input gain is close to minimum value of AGC. Check
RED
the input gain & route. Continue monitoring
The input gain is close to the maximum value of AGC.
RED
Check the input gain & route. Continue monitoring the
device.
RF input gain is close to margin. Adjust the input gain to
RED
eliminate the warning. If the warning light remains on,
return the transmitter for repair
The rear fan is faulty. The transmitter needs to be
RED
repaired.
The RF drive power entering the modulator is low. The
RED
CNR performance can be improved by increasing OMI.
The RF drive power entering the modulator is high. The
RED
distortion performance can be improved by decreasing the
OMI.
