AS you mentioned this maps to interface ge-0/0/23 and if show chassis hardware output is provided i can confirm you
Probably these logs are issue is seen more often when non-Juniper SFPs are used, because different SFP makers handle SFP monitoring in different ways. As long as you are not seeing a traffic impact along with the power warning, the message is safe to ignore.
I have gone through all the logs and found below suspicious logs are appearing for SFP of FPC 0 –
When a low power condition is detected on an SFP, a message similar to the following appears in the Syslog:
The bus that the router uses to monitor the SFP and update diagnostic data is called "i2c" or IIC, for an inter-integrated circuit. Conditions sometimes arise that cause the i2c to miss updates. As a result, you might see warnings and alarms regarding low power that subsequently clear. These should not affect traffic in any way.
This issue is seen more often when non-Juniper SFPs are used because different SFP makers handle SFP monitoring in different ways.
Since we are receiving the low power, So I would suggest you to please re-insert or swap out the SFP at the remote end and then check if these logs are still appearing or not.
